PdfSettings (serde, camelCase) is the Save PDF model: Standard, Compatibility
PDF 1.4-2.0, General (Preserve editing, Thumbnails, Fast web view, View after
saving, Create layers), Compression, Marks and Bleeds, Output, Advanced and
Security. PdfOptions = settings + pages, title and date.
document.exportPdf {path?, preset?, artboard?|artboards?|range?, standard?,
compatibility?, ...sections} -> {path|dataBase64, bytes, warnings} applies the
options over the preset (null keeps the preset's value); PDF/X, passwords,
PDF/A-2b at 2.0 and out-of-range values are refused; options accepted but not
applied yet come back as warnings. document.export {format: pdf} and
document.formats take and list the same options.
The Save PDF dialog (file.export.pdf, ui.savePdfDialog) has Preset,
Standard and Compatibility on top and a section list; it runs the export
before asking for a path, so bad options never open a save dialog.

Each <text> is swapped for a placeholder group before usvg runs, so the text keeps its z-order,
parent group, clip, mask, opacity, link and <use> instances, and usvg resolves its gradient and
pattern paints (in text space). <textPath> becomes type on a path (startOffset, side, anchor),
vertical writing-mode type on a vertical path. Per-character x/y/dx/dy/rotate lists become line
breaks (bounded), kerning (absolute x measured against the layout), baseline shift and rotation;
baseline-shift, numeric and relative weights (style names), letter/word spacing, kerning and the
character stroke's cap, join, miter and dashes are kept. The style cascade supports type, #id,
multiple-class, attribute, descendant and child selectors with !important and specificity.
<pattern> paints become pattern swatches. The import fuzz covers the new attributes and CSS.

import_fuzz now also feeds garbage and mutated `.vcswatches`, `.gpl`,
`.vcstyles` and `.vcflattener` files through `swatch.library.load` /
`graphicStyle.loadLibrary` / `flattener.presets.import`, uses what loads
(adds and applies the swatches and styles, previews and flattens with the
presets) and renders and exports the result. The SVG generator gains `<a>`,
Lab colours, mask options (`mask-type`, `data-vectorcraft-mask`) and paint
attributes. `PROPTEST_CASES` now raises the case count as the file's docs
say (an explicit `cases: 64` used to override it).

Shipped code no longer unwraps, expects or panics: every one of the 124
unwrap()/expect()/panic!/unreachable! sites outside tests now handles the
failure (Result/Option, ?, let-else, defaults) and reports errors to the user.
- Lints: workspace clippy denies unwrap_used, expect_used, panic, todo,
unimplemented and unreachable; clippy.toml allows them in tests, and
integration tests, examples and testkit opt out explicitly.
- Safety net (vectorcraft_engine::guard): a panic in a top-level command rolls
the document back and returns EngineError::Internal; a panicking tool is
reset; the MCP server answers with an internal error and keeps serving; the
UI frame and each control request are guarded.
- APIs that hid failures now return them: Rendered::to_png/to_jpeg/to_webp
return Result (JPEG/WebP errors used to write empty files),
FontDb::face returns Option, Region::top returns Option.
- Fuzzing: engine/tests/import_fuzz.rs feeds garbage, hostile and mutated SVG
and PDF through import → render → export (30k cases locally, no panics).
- Docs: AGENTS.md/CLAUDE.md rule, docs/development.md "Robustness" section,
README pointer and a PR template checklist.

The engine unit tests share one process, and two colour-management tests
switched the process-wide Color Settings (the working RGB space to the wide
gamut profile, Black Point Compensation off) for a moment. Any test that
showed or rendered a colour at that moment saw it through the wrong profile:
clicking_an_image_samples_its_pixel read #008181 instead of #008080.
- Move the two tests that change the Color Settings to their own test
binary (crates/engine/tests/color_settings.rs), so no unit test can see
non-default settings.
- The image-sampling test compares the stored colour, not its display hex.
- every_command_survives_empty_params toggles the process-wide proof view
(Proof Colors, Overprint Preview, Separations), so it now takes the
colour-management test lock like the tests that read that view.

- New original DrawCraft mark (gradient + pen nib) replaces the two-letter badge
- render: thumbnails and pattern tiles use a single-threaded context (vello's default is
multithreaded and panics on filters); per-item raster effects detected
- Type tool state no longer leaks across documents
- ui.set {status} for clean screenshots
- README: new hero, feature shots, Made in DrawCraft gallery; examples/neon-drive, ribbons,
feature-sheet; ASSETS.md updated; heading renamed to Crafting Apps
