Fix tiny icon on the 3D stage create-from-image button

- Safelist the lucide class so the icon sizing rule is no longer purged
  and icons scale with their text instead of rendering at 24px
- Use the webapp home colors for the apps page and apps menu tiles, and
  the webapp badge style on the apps page
- Match the top menu active and hover states to the webapp nav, and
  shrink its tooltips to plain 12px text
- Align toggle buttons (Instrumental, sound, etc.) and @Characters with
  the popover triggers beside them

 1. [Install Rust](https://doc.rust-lang.org/cargo/getting-started/installation.html).
 2. [Install npm](https://nodejs.org/en/download) or [nvm](https://github.com/nvm-sh/nvm). (Node version `v24.13.0` works at time of writing.) 
-3. [Install nx](https://nx.dev/docs/getting-started/installation). (Nx version `v22.4.5` works at time of writing.)
+3. The frontend's Nx and Vite dependencies are installed locally with npm; a global Nx installation is not required for the combined Unix launcher.
 4. [Install Tauri CLI](https://v2.tauri.app/reference/cli/). (Version `tauri-cli 2.10.0` works at time of writing.)
 
-An easy way to get started with running the app in development is to run the two commands (in separate terminals):
-
 **Mac and Linux Development** 
 
 ```bash
-# Run the frontend dev server
-./script/artcraft/unix_frontend_dev.sh
+# Start the frontend and Rust/Tauri together in one terminal
+./script/artcraft/unix_dev.sh
 
-# Run the Tauri Rust application
-./script/artcraft/unix_rust_dev.sh
+# Optionally start the free-port search at another port
+ARTCRAFT_DEV_PORT=6200 ./script/artcraft/unix_dev.sh
 ```
 
+Use the combined launcher instead of starting the two legacy dev scripts. It
+works from any working directory when invoked by its path and installs frontend
+dependencies if the local Vite installation is missing. Node.js 20+ is required.
+
+The launcher binds Vite to `127.0.0.1`, starting at port **5193** and trying
+successive ports until one is available. It leaves existing listeners alone.
+Only after the real frontend socket is bound does it start Tauri with that exact
+`devUrl`. HTTP and the HMR websocket share the selected port; Rust communicates
+through native Tauri IPC and needs no separate HTTP port. Configuration overrides
+are passed in memory, without changing the checked-in Tauri config.
+
+The native HTTP bridge normalizes loopback development origins for first-party
+API requests so an automatically selected port does not break login or media
+loading. See the [desktop session regression checks](../docs/desktop-session-regression.md)
+when changing ports, the launcher, or authentication.
+
+JavaScript, TypeScript, React, and CSS changes use Vite hot reload; compatible
+React component edits use Fast Refresh. Changes that cannot be hot-replaced
+reload the page. Rust changes use `cargo tauri dev`'s automatic **rebuild and app
+restart**, including dependent workspace crates. SQLx metadata and SQLite
+migrations are also watched. Rust reload is a process restart, so it does not
+preserve unsaved in-memory app state. See [Tauri's watch behavior](https://v2.tauri.app/develop/#reacting-to-source-code-changes).
+
+After startup, a Vite configuration restart must reuse the chosen port or report
+an error; it cannot silently switch to another port while Tauri uses an old URL.
+Ctrl-C stops this session's frontend, Rust watcher/compiler, and desktop app.
+If the Rust watcher exits, the launcher closes Vite and propagates the exit code.
+It never finds or terminates another app by name or port.
+
+The launcher retains the existing Unix defaults for `VITE_ENVIRONMENT_TYPE`,
+`SQLX_OFFLINE`, `RUSTFLAGS`, and the Linux WebKit workarounds. Explicit environment
+overrides are preserved. It uses the normal Artcraft app data and Cargo target
+directory; port separation does not create an isolated account/data profile, and
+concurrent Rust builds can wait on Cargo's build lock.
+
+To verify the launcher without compiling Rust or opening a desktop window:
+
+```bash
+node --test frontend/scripts/unix-dev.test.mjs
+```
+
+The tests use real Vite listeners and HMR, with a test-owned fake Cargo process
+tree. They cover occupied ports, simultaneous launches, React edits, shutdown,
+Rust-process failure, and watcher arguments. To verify native Rust reload, run
+the launcher, wait for the desktop window, make a Rust source edit, and check for
+a rebuild/restart in the same terminal. Frontend edits should update the webview
+without restarting the Rust process.

+Rust HTTP endpoint bindings used by the ArtCraft Tauri desktop app.
+
+## Endpoint layout
+
+- Each HTTP endpoint binding must live in its own descriptively named `.rs` file.
+  This applies to both free functions and methods implemented on a shared client.
+  Do not combine several routes into a catch-all file such as `login_challenges.rs`
+  or `password_auth.rs`.
+- Group related bindings in a directory module. Keep `mod.rs` for module declarations;
+  it must not contain endpoint implementations. For example:
+  `endpoints/users/login_challenges/create_login_challenge.rs` and
+  `endpoints/users/login_challenges/poll_login_challenge.rs`.
+- Keep each endpoint's route constant, request construction, and endpoint-specific
+  request/response types in its file. Keep shared wire types in `artcraft_api_defs`
+  or a dedicated shared type module; do not duplicate them across endpoint files.
+- Put shared HTTP transport, client setup, and common error handling in a separate
+  utility module. A transport module must not accumulate endpoint bindings.
+- Update callers to import types from their new modules when splitting bindings.
+  Preserve request methods, paths, headers, error behavior, and cookie handling.
+
+## Validation
+
+Run `cargo check --offline -p artcraft_client` for client changes. For native login
+bindings, also run `SQLX_OFFLINE=true cargo test --offline -p artcraft --lib
+login_bridge_tests`; these tests use local HTTP fixtures and temporary cookie jars.

+# Tauri Commands
+
+- Put each `#[tauri::command]` function in its own `.rs` file module named after
+  that command, such as `storyteller_create_login_challenge_command.rs`. Do not
+  collect multiple commands in a catch-all `*_commands.rs` file.
+- Keep `mod.rs` for module declarations. Put shared state, response/error types,
+  and implementation helpers in separate support modules, with the narrowest
+  visibility needed by their callers.
+- Update the imports used by `tauri::generate_handler!` when moving commands.
+  Preserve IPC command names and arguments unless changing that contract is
+  explicitly part of the task.
+- Authentication HTTP requests run in Rust through `artcraft_client` endpoint
+  bindings. The frontend invokes Tauri commands; it does not call the API
+  directly, and desktop commands do not connect to the backend MySQL database.
+- For login bridge changes, run the existing native fixture tests with
+  `SQLX_OFFLINE=true cargo test --offline -p artcraft --lib login_bridge_tests`.
+  These tests use loopback HTTP servers and temporary cookie stores.

+# Desktop session regression — September 27, 2026
+
+The combined development launcher (`92e6f438c3`, following the performance
+change `df707bf8e1`) moved Vite from `localhost:5173` to an available port on
+`127.0.0.1`. The vendored HTTP plugin forwarded that webview Origin to the
+production API. The API rejected it with **400: Origin is not allowed to make
+this request**.
+
+The native login bridge and credits commands use a different HTTP transport and
+continued working. Consequently the login modal correctly recognized the native
+session, but Accounts, Library, and page media requests failed. Accounts treated
+the error as logged out; its Log In button rechecked the valid native session
+and immediately closed the login modal again.
+
+The fix extends the existing packaged-desktop Origin normalization to loopback
+development origins, at any port, for HTTPS requests to `api.storyteller.ai` and
+`api.fakeyou.com`. Other development request destinations and non-loopback
+website origins retain their headers. Cookie handling and API authorization are
+unchanged. A frontend reload alone cannot update this fix: Rust must rebuild.
+
+## Dedicated desktop origin and rollout
+
+The desktop app now declares itself per destination. Both transports read the
+values from one place, `crates/lib/artcraft_client_identity`
+(`Destination::classify`, origins, user agents, third-party provider table):
+
+| Destination                                            | Origin sent                         | User-Agent               |
+|--------------------------------------------------------|-------------------------------------|--------------------------|
+| Our APIs (`api.storyteller.ai`, `api.fakeyou.com`, …)  | `https://desktop.getartcraft.com`   | `storyteller-client/1.0` |
+| Local API (`localhost`, `127.0.0.1`, `[::1]`)          | `http://localhost`                  | `storyteller-client/1.0` |
+| Our CDNs / sites (`*.storyteller.ai`, `*.fakeyou.com`) | unchanged (`studio.storyteller.ai`) | `storyteller-client/1.0` |
+| Named third parties (`THIRD_PARTY_PROVIDERS`)          | the provider's own site             | OS webview               |
+| Any other host (incl. `storage.googleapis.com`)        | webview origin, untouched           | OS webview               |
+
+- The native Rust client (`artcraft_client`) sends the Origin and User-Agent on
+  every API request via `storyteller_client_builder`; it previously sent no
+  Origin.
+- The "OS webview" User-Agents are hardcoded snapshots in
+  `artcraft_client_identity/src/user_agents.rs` and go out of date as the
+  webviews update (notably WebView2's Edge version on Windows). Refresh them
+  from `navigator.userAgent` in the desktop app's devtools on each OS.
+- The vendored HTTP plugin only replaces the webview's own origin (packaged
+  `tauri://localhost` etc., or a loopback Vite origin), and only sets the
+  User-Agent when the frontend didn't.
+- Native third-party Rust clients (Grok, Midjourney, Sora, World Labs, Kinovi)
+  set their own headers and are not affected.
+- Older desktop releases keep working: the server still allows the studio and
+  Tauri origins, and requests without an Origin.
+
+Keep the deployed origin in sync with
+`../artcraft-services/crates/lib/actix_cors_configs/src/configs/artcraft_desktop.rs`.
+Development servers accept any `localhost` origin.
+
+Deploy the server allowlist to the APIs **before running or releasing a desktop
+build with the new origin**. Otherwise the deployed server will reject desktop
+requests until its allowlist is updated. The server retains the studio and
+legacy Tauri origins so existing desktop releases continue working.
+
+Check both repositories:
+
+```sh
+# From artcraft/
+cargo test --offline -p artcraft_client_identity -p tauri-plugin-http --lib
+
+# From artcraft-services/
+cargo test --offline -p actix_cors_configs --lib
+```
+
+The server tests verify credentialed GET/POST requests and OPTIONS preflights in
+production and development, rejection of lookalike domains/HTTP/alternate ports,
+and compatibility with previous desktop origins. After server deployment, repeat
+the native checks below using the updated app.
+
+## Observed native results
+
+These observations were captured with the earlier studio origin, before the
+dedicated desktop origin migration. They do not establish that production has
+deployed the new allowlist.
+
+Checked in the real macOS Tauri dev app at `http://127.0.0.1:5193`, using its
+existing session. Temporary probes were removed after verification. No cookies,
+tokens, passwords, account identifiers, or media contents are recorded here.
+
+| Check                          | Before                                | After                      |
+|--------------------------------|---------------------------------------|----------------------------|
+| Frontend HTTP `/v1/session`    | 400, Origin rejected                  | 200                        |
+| Shared `UsersApi.GetSession()` | `success: false`                      | Success, logged in         |
+| Native vs. frontend identity   | Frontend could not resolve an account | Same account               |
+| Shared media API, page size 1  | Not measured separately               | Success, one item returned |
+
+## Automated checks
+
+From the repository root:
+
+```sh
+cargo test --offline -p tauri-plugin-http artcraft_origin --lib
+./script/artcraft/unix_dev.sh
+```
+
+In a second terminal, substitute the URL printed by the launcher:
+
+```sh
+cd frontend
+npm run test:desktop-session -- http://127.0.0.1:5193
+```
+
+The Rust tests cover the default port, alternate/collision ports, IPv4, IPv6,
+localhost, packaged origins, duplicate headers, session-header preservation,
+and destinations/origins that must remain unchanged.
+
+The browser check uses the real frontend with an isolated Chrome profile and
+mocked IPC. It verifies matching credits and Accounts state, a visible Library
+image, media after opening the deferred image page, video/audio page rendering,
+and logout followed by sign-in. It blocks remote browser traffic and never uses
+your real account or native credentials. It requires installed Google Chrome.
+It can also run against a locally served production frontend build.
+
+These browser mocks cannot validate native transport or server CORS. The
+performance fixture deliberately rejects HTTP requests and is **not** an
+authentication acceptance test. Run the native check below when changing the
+launcher, HTTP bridge, or authentication plumbing.
+
+Validation on September 27: all 12 HTTP-plugin tests, 20 login-modal tests, and
+10 app tests passed. The browser check passed against both the Vite dev server
+and a fresh production build. To repeat the production check, serve a build in
+one terminal, then pass its printed URL to `test:desktop-session` in another:
+
+```sh
+cd frontend/apps/artcraft
+npm run build -- --outDir /tmp/artcraft-session-build
+npm run preview -- --outDir /tmp/artcraft-session-build --host 127.0.0.1 --port 6215
+```
+
+## Repeat the real native check
+
+1. Start the combined launcher, with an existing signed-in test session. Verify
+   Accounts displays that account, My Library loads its media, and Create Image,
+   Create Video, and Create Audio load their content.
+2. Right-click inside the desktop webview, choose **Inspect Element**, and open
+   **Console**. Run this read-only probe. It prints statuses/counts, not credentials
+   or account/media contents:
+
+```js
+void (async () => {
+  const invoke = window.__TAURI_INTERNALS__.invoke;
+  const host = (await invoke("get_app_info_command")).payload.storyteller_host;
+  const options = { method: "GET", credentials: "include" };
+  const started = performance.now();
+  const [native, response] = await Promise.all([
+    invoke("storyteller_get_login_session_command"),
+    window.FetchProxy(`${host}/v1/session`, { ...options }),
+  ]);
+  if (!response.ok) {
+    console.log({ origin: location.origin, sessionStatus: response.status });
+    return;
+  }
+  const session = await response.json();
+  const result = {
+    origin: location.origin,
+    sessionStatus: response.status,
+    nativeLoggedIn: !!native,
+    frontendLoggedIn: session.logged_in,
+    sameAccount: native?.user_token === session.user?.user_token,
+    sessionElapsedMs: performance.now() - started,
+  };
+  if (session.logged_in && session.user) {
+    const username = encodeURIComponent(session.user.username);
+    const media = await window.FetchProxy(
+      `${host}/v1/media_files/list/user/${username}?page_size=1`, { ...options },
+    );
+    result.mediaStatus = media.status;
+    if (media.ok) result.mediaCount = (await media.json()).results?.length;
+  }
+  console.log(result);
+})().catch((error) => console.error("Desktop session probe failed", String(error)));
+```
+
+3. Repeat with a changed port (`ARTCRAFT_DEV_PORT=6200`) and with the starting
+   port occupied. For example, keep this listener running in another terminal
+   before starting the launcher; stop it with Ctrl-C afterward:
+
+```sh
+node -e 'require("node:net").createServer().listen(5193, "127.0.0.1")'
+```
+
+The launcher should select a later port, and both session transports should
+still agree. An empty account may legitimately return zero media; it should
+still return HTTP 200. Verify a genuinely signed-out session shows the login
+screen using the isolated browser check, or a disposable account/profile.

+# Desktop frontend performance experiments
+
+Measured September 26, 2026 on an Apple M4 Pro, macOS arm64, Chrome
+153.0.8010.53, Node 24.13.0. These are production frontend measurements in
+headless Chrome with mocked Tauri services. They do **not** measure native
+process launch, WKWebView/WebView2, Rust, disk startup, real account loading,
+or generation latency.
+
+These timings are not authentication acceptance tests: the benchmark mocks the
+native session and rejects frontend HTTP requests. Before accepting a desktop
+change, also run the [session and Library checks](desktop-session-regression.md),
+including real Tauri HTTP requests when changing the launcher or bridge.
+
+## Changes and results
+
+Seven samples per version; table values are medians. Each sample uses a fresh
+browser context at 1440 × 1000 with device scale 1 and browser HTTP cache
+disabled. The browser process stays alive between samples. A reload in the
+same context is measured separately. There is no CPU/network throttling.
+External requests, including analytics, fonts, and media, are blocked in both
+versions. The login fixture is signed in; the bundled model overlay is used.
+
+| Measurement                 | Before    | After     | Reduction |
+|-----------------------------|-----------|-----------|-----------|
+| Startup to frame            | 566.40 ms | 350.60 ms | 38.1%     |
+| Refresh to frame            | 248.60 ms | 198.10 ms | 20.3%     |
+| Startup JavaScript          | 9.05 MB   | 6.47 MB   | 28.6%     |
+| Startup long tasks (sum)    | 336.00 ms | 184.00 ms | 45.2%     |
+| First drawing page to frame | 120.90 ms | 118.20 ms | 2.2%      |
+| Drawing to home: dispatch   | 23.40 ms  | 9.00 ms   | 61.5%     |
+| Drawing to home: frame      | 29.50 ms  | 23.00 ms  | 22.0%     |
+| Home to drawing: dispatch   | 42.10 ms  | 18.80 ms  | 55.3%     |
+| Home to drawing: frame      | 105.70 ms | 86.50 ms  | 18.2%     |
+
+The 2.2% first-open difference is small enough to treat as unchanged. These
+local measurements are evidence of reduced frontend work, not predictions
+of identical percentage gains on every user's machine. Raw samples, ranges,
+environment, fixture sizes, browser errors, and build provenance are in
+[before.json](performance/2026-09-26-before.json) and
+[after.json](performance/2026-09-26-after.json).
+
+Three changes produced these results:
+
+1. `MainApp.tsx` imported every editor at launch. Fifteen pages now use
+   `React.lazy` behind a Suspense boundary below the persistent shell. Their
+   code loads when selected; the top bar stays available during loading.
+   The default Apps page remains eager. Drawing also remains eager: its
+   shared code is already part of the shell, and experimentally deferring
+   its small host adapter made first-open latency worse for little saving.
+   First-open latency for the other deferred editors is a remaining tradeoff
+   to measure, especially on slower disks/CPUs. All 15 deferred modules were
+   imported successfully in the browser, but this is not an end-to-end test
+   of every editor's features.
+2. `TabState.ts` exported the drawing scene to JSON when leaving and imported
+   it when returning. The Zustand scene store already survives page unmount.
+   With four imported images, the old path performed four FileReader reads
+   on exit and four more on return, allocated base64 copies, rebuilt image
+   nodes, cleared the selection, and appended an undo-history entry. Tab
+   changes now keep the live store. The measured round trip performs **zero
+   image-file reads**, preserves the selected node, and keeps history length
+   at one instead of growing to two. Explicit file export/import remains
+   available. Tests cover image identity, model metadata, selection, redo,
+   gallery reset, rapid navigation, and portable file export.
+3. The shell ran `getGPUTier()` at startup and stored its result in an unread
+   React state value. Removing it eliminates **one startup WebGL context
+   request** and its associated detection work. The real 3D renderer still
+   creates its context when used. This experiment reports combined timing
+   gains, not an isolated timing attribution for each individual change.
+
+## Repeat the experiment
+
+From the repository root:
+
+```sh
+cd frontend
+npm ci
+npm run perf:desktop -- --output /tmp/artcraft-perf-current --smoke-imports
+```
+
+The default browser is an installed Google Chrome (`--channel chrome`). The
+runner requires permission to launch a browser and bind a loopback server.
+It never uses your regular browser profile, account, or native app data.
+`@playwright/test` is pinned as a development dependency. Artifacts are written
+outside the repository by default. Use a dedicated output directory: its
+`dist` subdirectory is rebuilt by Vite.
+
+For this particular two-module change, reproduce the original implementation
+without replacing local source files:
+
+```sh
+npm run perf:desktop -- --output /tmp/artcraft-perf-before \
+  --baseline-ref 780e4494e995163fed1d677b88c3cf03b3fca63c
+npm run perf:desktop -- --output /tmp/artcraft-perf-after --smoke-imports
+node tools/performance/compare.mjs \
+  /tmp/artcraft-perf-before/results.json \
+  /tmp/artcraft-perf-after/results.json
+```
+
+`--baseline-ref` overlays **only** `MainApp.tsx` and `pages/Stores/TabState.ts`
+from that Git revision in the benchmark build. All other source files and
+dependencies remain current. It reproduces the two production files changed
+in this experiment; it is not a general historical-checkout benchmark. For
+future changes, capture a normal baseline **before** editing, use a new output
+directory for the changed version, and keep the runner, fixture, dependencies,
+browser, and machine identical. Run sequentially while the machine is idle;
+do not build or run other CPU-heavy tasks during samples. Repeat in reverse
+order if results are close or noisy.
+
+Useful options:
+
+```sh
+# Build in a restricted shell, then run where browser/server use is allowed.
+npm run perf:desktop -- --output /tmp/artcraft-perf-current --build-only
+npm run perf:desktop -- --output /tmp/artcraft-perf-current --skip-build
+
+# More samples; seven is the default.
+npm run perf:desktop -- --output /tmp/artcraft-perf-current --runs 15
+
+# Correctness checks for the navigation change.
+npx vitest run --config apps/artcraft/vitest.config.ts
+```
+
+Do not use `--skip-build` after changing app code; it intentionally measures
+the existing artifact. `build-info.json` records the revision, changed-file
+names, baseline overlay, and build time. The benchmark plugin alone exposes
+the stores needed to seed the scene. It is not part of the normal Vite/Tauri
+build, and no mock IPC or benchmark global is added to the shipped app.
+
+The runner builds from the app's working directory, matching its normal
+build command. This matters because Tailwind resolves its config and content
+relative to that directory. It rejects a run without working Tailwind styles
+or with uncaught browser errors. `drawing.png` provides a visual check after
+the measured operations. The initial unstyled exploratory runs were discarded.
+
+## What the measurements mean
+
+The fixture creates four deterministic 1024 × 1024 PNG image nodes and 80
+strokes of 200 coordinates each, with one selected image. On the recorded
+browser each PNG is 2,356,706 bytes. Fixture construction, image decoding,
+and a one-second settling period are outside the tab-transition timings.
+Each sample follows the same sequence:
+
+1. Navigate to the production app, wait for the Apps heading and for the
+   signed-in login overlay to disappear, then wait two animation frames.
+2. Reload that page and repeat the same readiness checks.
+3. Seed the scene while on Apps, open drawing, and wait for its canvas and
+   two animation frames. Allow a second for its background bake to settle.
+4. Switch to Apps and then back to drawing, measuring each separately.
+5. After a settling period, inspect node count, selection, history, and IPC
+   counters. Save a screenshot on the first run. Optionally evaluate all
+   deferred page modules after the final timed operation.
+
+`readyMs` is `performance.now()` after readiness checks and two animation
+frames; its origin is navigation start. It includes browser loading and
+automation readiness-observation overhead. `jsBytes` sums decoded resource
+sizes of loaded JavaScript; it is uncompressed bytes, not all packaged files.
+`longTaskMs` sums observed startup tasks longer than 50 ms, not total CPU time
+or total blocking time. Long Tasks support is browser-dependent.
+
+`stateReadyMs` measures the awaited `setActiveTab()` action, including React
+work synchronously flushed by its store subscribers. `paintMs` continues
+until the destination heading/canvas exists and two animation frames have
+passed. This is a **rendering-opportunity proxy**, not proof of GPU presentation
+or of every asynchronous image decode completing. In particular, the old
+return path could still be decoding images after the canvas first appeared.
+Tab measurements also create `artcraft:tab:APPS` and `artcraft:tab:2D` User
+Timing entries in the benchmark page.
+
+The runner calls the same store action used by navigation UI. It excludes
+pointer-event dispatch, menu animations, and physical click-to-screen latency.
+It does not automate paid generations, sign in to a real account, or measure
+remote services. Save the raw JSON as well as the summary; a single minimum
+time is not a reliable comparison.
+
+`dist/performance-bundle.json` ranks the largest retained modules per chunk
+and records chunk imports. Module `renderedBytes` is Rollup's intermediate
+module size; it is useful for attribution but should not be summed as final
+minified/gzipped size. Use actual resource bytes for the startup total.
+
+## Remaining investigation
+
+- The shell still loads about 6.47 MB of JavaScript. Shared imports through
+  drawing, scene, gallery, and settings entry points need a deeper dependency
+  audit. Separate lightweight store/type imports from editor code, then use
+  the bundle report and the same startup experiment to verify what actually
+  leaves the initial graph. The report identifies Spark, Three.js core and
+  renderer, the inline FBX-to-GLB conversion worker, PostHog, and Mediabunny
+  among the largest retained modules. Their presence is measured; the runtime
+  benefit of deferring each individually has not yet been measured.
+- Returning to the populated canvas still takes about 86 ms. The editor
+  remount, Konva drawing, image/transformer setup, and composite bake need a
+  timeline profile before choosing the next change. Keep scene restoration,
+  undo, selection, and background generation behavior in correctness checks.
+- `TaskQueue.tsx` polls every five seconds and rebuilds task arrays even when
+  the popover is closed. The benchmark uses an empty queue, so it does not
+  establish the cost for a large real queue. A fixed, representative task
+  fixture plus idle CPU/render counts is the next useful experiment there.
+- `useStageSnapshot` looks expensive in isolation, but its only call is
+  commented out in `PaintSurface.tsx`. It was excluded as a current bottleneck.
+
+Validation completed: normal production Vite build, all 10 app tests and 20
+login tests, all 15 deferred page-module imports, visual canvas inspection,
+and a check that the normal build contains no benchmark globals or fixtures.
+The broad TypeScript check remains blocked by existing workspace declaration/
+project-reference errors and Remix/Deno types. Comparing diagnostics with the
+two original modules showed the same diagnostic messages (some import traces
+and reporting locations changed); this is not a clean typecheck claim.
+
+## Validate in the native app
+
+Before claiming native launch or interaction gains, run matching release
+Tauri builds on the same machine and WebView version. Keep account, window
+size, network conditions, and canvas artwork fixed. Record the Web Inspector
+timeline for launch/reload, opening a tool for the first time, drawing → Apps,
+and Apps → drawing. Repeat at least seven times and retain the traces with
+build IDs and medians. Separate native process launch from page reload; do
+not mix dev/HMR traces with production measurements.
+
+For canvas tests, create a blank 1024-square canvas, import the same four
+images, add the same strokes, select an image, and wait for background work
+before switching. Check image content, selection, undo/redo, and opening a new
+gallery image afterward. Record actual click-to-visible-frame latency in
+the inspector as well as JavaScript tasks. The browser results above justify
+the code changes but do not replace that native validation.

+# Website login from the desktop app
+
+The React login/signup dialog calls Tauri commands only, including its startup
+session check and password forms. Website and QR actions appear only in login
+mode. Tauri never connects to MySQL; the desktop uses Rust HTTP API bindings. Creating/polling login challenges and
+verifying `/v1/session` use `artcraft_client::endpoints::users::login_challenges`.
+The Rust command uses `AppEnvConfigs.storyteller_host` for every request, keeps the
+private device token in native memory, and returns only a local challenge handle,
+approval URL/code/deadline, status, and the verified user to JavaScript. The signed
+session cookie never crosses IPC or gets written to JavaScript local storage.
+
+After redemption, Rust verifies the signed session against the same API host,
+installs the server's cookie into the native HTTP jar and credential manager, and
+persists the jar. Closing the dialog removes the local handle; a cancellation
+while HTTP is in flight prevents installing the late response. Retries retrieve
+the same server session. Neither creation nor website approval pre-creates one.
+
+## Session response compatibility
+
+A server feature flag added after a desktop release must not prevent login. The
+session decoder keeps known feature flags and ignores unknown flag names, such
+as `use_qt` on older clients. Malformed flag values and required authentication
+fields still fail validation. Tests cover a real Rust HTTP session response with
+both known and future flags, followed by native cookie installation/persistence.
+A late startup session check cannot reset an active or completed website login.
+
+## Diagnosing 401 responses
+
+`storyteller_activity_thread` reports errors from `/v1/analytics/active_user_v2`.
+This is the background activity ping, not the login-challenge endpoint. It requires
+a user session. An anonymous `visitor` cookie alone is now skipped. Expired or
+revoked sessions can still produce a 401 and require signing in again.
+
+Activity failures log the configured API origin (including port), endpoint, and
+error. Native website-login requests/failures log origin, endpoint, and HTTP
+status. Request bodies, device tokens, approval URLs, and signed cookies are not
+logged by the new client, including at debug level.
+
+## API environment
+
+`~/Artcraft/settings/env_configs.json` controls the native API host:
+
+```json
+{"storyteller_host":"localhost","storyteller_port":12345}
+```
+
+Local mode uses `http://localhost:12345` and a local approval website at
+`http://localhost:4201/login/desktop`. Run storyteller-web with its migrations
+applied, and the services webapp with `USE_LOCAL_API=1`. The local website must
+also use the local API. A challenge in a local database cannot be approved on the
+production website, even when that browser already has a production session.
+
+For the production API and production website, use `"storyteller_host":"production"`
+(or omit the override), then restart ArtCraft. API host configuration is not
+silently changed by login. Local and production approval URLs cannot be mixed.
+Localhost development URLs are for the same computer; mobile QR testing needs
+a shared/deployed environment.
+
+## Tests
+
+From the desktop repository:
+
+```sh
+SQLX_OFFLINE=true cargo test --offline -p artcraft --lib login_bridge_tests
+cd frontend
+npm exec vitest -- run --config libs/components/login-modal/vite.config.ts src/lib/DesktopLoginBridge.spec.tsx src/lib/login-modal.spec.tsx
+```
+
+Native tests use only ephemeral loopback HTTP servers and temporary cookie stores.
+They exercise the real API bindings and the command implementation, including
+cookie verification/persistence, rejection, expiry, retries, in-flight cancellation,
+origin separation, no redirects, redacted errors, visitor-only telemetry, future
+feature flags, malformed session data, and password login/signup/session checks.
+UI tests prohibit JavaScript HTTP and runtime API imports. They verify the IPC
+contract, native browser opening, QR/code display, status, backoff, cleanup,
+login-only button placement, native password forms, and stale session responses.
+
+The services repository also has real MySQL integration tests for approval,
+redemption, rejection, concurrency, and downstream authentication, using isolated
+local databases. No test contacts a production API or database.
