User and imported .abr brush presets now survive a restart. The new
photocraft_engine::preset_store keeps one JSON file per preset group plus
content-addressed, deflated tip bitmaps (8-bit when the tip came from 8-bit
data) in <config dir>/Presets, and an index with group order and deleted
built-ins. Built-ins are never written; writes are atomic and bounded;
corrupt or oversized files are skipped with a warning and left on disk.
The desktop app loads the store on a background thread and attaches it when
it arrives; sessions without a store (CLI, MCP, web, tests) stay hermetic.
Brush preset mutations bump ToolState::presets_rev and the store syncs after
the command, rewriting only groups whose content changed.

* Compose: render in place and in bands; area-reduced and proxy thumbnails
render_tiled wrote every tile into a Vec and then copied them into the output:
two full-size float copies (6.3 GB for a 14000² document). Tiles are now
written straight into the output band by band.
New streaming APIs so large documents never need a full-size float
composite: render_bands (sink per band of ~8 MP), render_reduced (banded
area average, bit-identical to the old flatten-then-average thumbnail) and
flatten_to_surface (Flatten Image, Merge Visible, Copy Merged and the other
flattened-surface users).
thumbnail() reduces a downsampled proxy (moved from ui-egui to
compose::proxy, now also scaling spot channels) for documents over 16 MP
when that is faithful (no layer effects or vector masks), so navigator,
channel and histogram thumbnails of a 196 MP document cost milliseconds.

* GPU canvas: request the adapter's real limits; banded CPU fallback; navigator thumbnail
egui-wgpu asks for an 8192 px texture limit, so the wgpu compositor rejected
every document wider or taller than 8192 px and each refresh fell back to a
full CPU flatten. The desktop and web apps now request the adapter's own
max_texture_dimension_2d and max_buffer_size (gpu_canvas::use_adapter_limits);
the benches use the same limits.
The CPU fallback (documents beyond the GPU limit, or features it lacks) is
GpuCanvas::refresh: it renders and uploads the composite band by band
instead of a full float composite plus a full RGBA8 copy. The CPU canvas
texture is reduced in bands too, and the Navigator on the GPU canvas uses a
cached thumbnail instead of a full-resolution CPU composite per revision.

* IO: banded export and import; no full-size copies in encoders; larger decode limits
- Flat export renders the composite in bands and quantises each band; alpha
is dropped in place when every pixel is opaque. The single-layer native
path copies surface rows a band at a time (no f32 read_region and no
per-pixel Vec). Buffers come from try_reserve: Err, not an abort.
- PSD export encodes the merged image band by band into its planes (no
flatten, no second plane copy); near-opaque documents are re-encoded
without the white matte so the output is unchanged. Layer interleaved
bytes are freed before their planes are compressed.
- Flat import converts in ~32 MB bands (and not at all when already RGBA);
the PSD merged-image un-matte works per tile row.
- Encoders borrow the image when no conversion is needed (Image::converted)
instead of cloning it; PNG only copies 16-bit data for the byte swap.
- Decode limits: 2^30 pixels and 8 GiB on 64-bit targets (a 20000² JPEG
was refused at 2^28).

* Filters: write tile results in memory-bounded groups
apply_tiled collected every tile's float result before writing any (3.1 GB
for a 14000² layer). Results are now produced and written in groups of about
256 MB (at least one tile per core).

* History: bound pixel memory by Preferences > Performance > Memory Usage
History::max_bytes caps the current document's tiles plus the tiles only
history holds (layers, masks, alpha channels); History::trim drops the
oldest states beyond it after every recorded step and when preferences
change, always keeping the last step undoable. The engine sets it from
memory_usage_mb, which was unused.

* Large-image benchmark (14k / 20k): open, refresh, thumbnails, filter, stroke, saves
One operation per run on a cached synthetic photo, with the GPU device created
the way the app creates it, so /usr/bin/time -l reports that operation's peak
memory. Documented in docs/development.md.

* CMYK documents display and export through their embedded CMYK profile
A thread-local CmykSpace (photocraft_color::convert::with_cmyk_space) replaces the built-in
coated CMYK while the CPU compositor, the GPU compositor's uploads and the PSD merged
composite convert a document's CMYK pixels; GPU residents track the profile they were
converted with.

* Colour-managed canvas: document profile -> monitor profile on GPU and CPU paths
* engine display_color: CanvasDisplay per (document profile, mode, monitor), identity fast
path when they match (sRGB on sRGB costs nothing); linear composites are stored
sRGB-encoded in the 8-bit texture. canvas_lut now always carries the CM transform, with
Proof Colors / Gamut Warning / 32-bit preview on top.
* GPU canvas applies the display LUT whenever the transform isn't the identity (also for
filter/proxy previews); the CPU canvas and Navigator transform the 8-bit composite.
* Edit > Color Settings > Monitor Profile (auto|built-in|.icc). macOS 'auto' reads the main
display's ICC profile at launch via osascript/AppKit (no unsafe); elsewhere sRGB.
* Tests: P3 (hand-computed), Adobe RGB, ProPhoto, Gray Gamma 2.2, synthetic CMYK, linear,
monitor setting; GPU+CPU canvas test via kittest (skips without Rgba32Float).

* io: tag EXR/HDR linear in import_flat (adapt to the shared image_to_document)
#65 moved flat decoding into image_to_document(name, img) so camera raws can reuse it; the
linear-EXR tagging needs the file bytes for format detection, so it now runs in import_flat.

* raw: clean-room camera raw decoder and developer (photocraft-raw)
A new standalone crate (no workspace deps, wasm-safe, no unsafe) written
from TIFF 6.0, TIFF/EP, the DNG 1.7 spec, ITU-T T.81 Annex H and published
demosaicing papers:
- Lossless JPEG (LJ92) decoder: predictors 1-7, point transform, restart
intervals, combined Huffman+extra-bits fast table.

LinearRaw, linearization, black level (repeat, deltas), white level,
active area, default crop, ColorMatrix/CameraCalibration/ForwardMatrix
interpolation by CCT, AnalogBalance, AsShotNeutral/WhiteXY,
BaselineExposure, orientation.
- CR2 (LJ92 slices, SensorInfo borders, ColorData as-shot WB, measured
black) and TIFF/EP raws (NEF/ARW/PEF uncompressed or LJ92, incl. Sony
lossless ARW tiles, Nikon/Sony documented black and WB tags).
- Develop: black/white scaling, WB with highlight clipping, bilinear /
Malvar-He-Cutler / AHD demosaic (rayon bands, sequential on wasm),
camera -> XYZ D50 -> ProPhoto, exposure, gamma 1.8, 16-bit, orientation.

* File open/save: set the path everywhere, Open Recent, show errors and import/export warnings
File › Open, drag-and-drop onto the window and launch paths now share
PhotocraftApp::open_file: the document is named after the file (not the full
path), keeps its path so File › Save writes back, and goes to Open Recent.
Failures are shown as errors (status bar + a non-blocking notice).
Import/export warnings from photocraft-io are no longer thrown away: they show
in the status bar and in a dismissable notice (native and web), and the
control protocol returns them from app.open/app.save/file.open/file.save/
file.saveAs/file.saveACopy. .pcraft is in the Open and Save filters, and
File › Save writes .pcraft documents in place.

* macOS: open files from Finder, Open With and the Dock (Apple events)
Finder double-click, Open With, drops on the Dock icon and open -a deliver
files as kAEOpenDocuments Apple events, not argv, and winit 0.30 ignores them.
Register an NSAppleEventManager handler through the small fmv-macos-events
crate (MIT OR Apache-2.0, 168 lines, audited, pinned =0.1.0; it keeps the
Objective-C unsafe out of our forbid(unsafe_code) workspace) before the event
loop starts, so both the launching event and later ones reach the UI as
OsEvent::Open; the window is focused. The quit Apple event goes through the
normal close path.

- Session::execute wraps a command's run in catch_unwind: a panic that
escapes anyway becomes an EngineError ("`id` failed with an internal
error (logged); the document is unchanged"). Session::edit only commits
after its closure returns, so documents stay intact. This covers the
UI, CLI, MCP and control channels.
- apps/photocraft: a new crash_guard module installs a logging panic hook
(keeping the default one) and guards the native import/export services,
so a panic while opening or exporting a file is reported as an error
and the open documents stay. Wired in with two lines in main.rs.
- services::import_flat returns an error instead of unwrap; photocraft
and photocraft-web deny unwrap/expect/panic/unimplemented/todo/
unreachable.

- rpc::respond (the JSON-lines server behind `photocraft-cli run`/TCP)
catches a panicking request and answers it with an error, and keeps
using a poisoned session lock (as the MCP server already does) instead
of failing every later call with "session lock poisoned". Regression
test poisoned_session_keeps_serving.
- MCP server: the eight bridge_client().expect("bridge") and the
headless_op(..).expect("headless") calls return a tool error instead.
- bridge: the connection is taken with let-else, not expect.
- automation and photocraft-cli deny unwrap/expect/panic/unimplemented/
todo/unreachable.

CI's `cargo fmt --all -- --check` has failed on every run because the
repo had no rustfmt config and was never formatted. Use the same settings
as EffectCraft/FilmCraft (max_width 160, use_small_heuristics Max), which
also keeps the churn small. Formatting only; no code changes.

ctx.open_url is unreliable on native (notably Windows), so the Help menu,
the Discord buttons, and the start-page links did nothing. Added an open_url
Service hook wired to the `open` crate on native (ShellExecute on Windows);
links::open prefers it and falls back to ctx.open_url (web). link_row now
routes clicks through it instead of ui.hyperlink_to. Test drives every Help
link id + the open() helper through a mock service.
