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.

effect.expandAppearance now expands the whole appearance: each visible fill becomes a
path of its own and each stroke its outline (a brushed stroke its brush art), grouped
in paint order under the object's id and transparency; geometry effects are baked and
raster effects become an embedded image (shadows below the art, blur/feather/inner glow
replacing it). Type with effects or its own fills is outlined, and a group's or layer's
own fills and strokes are expanded among its members. The command is enabled whenever
an appearance isn't basic. Builds on bake_leaf (effects::expand_leaf / expand_art) and
shares the raster-effect image code with PDF export.
