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.

Adds LICENSE-MIT, LICENSE-APACHE and docs/brand/LICENSE-brand.txt from the Crafting Apps
licensing standard. NOTICE follows the standard template (copyright, licence, brand carve-out)
and keeps the third-party list, now noting the Feather-derived Lucide icons (also MIT) and the
egui default fonts compiled into the app. ASSETS.md gives the docs/brand/ files their trademark
terms and marks the 21 Feather-derived Lucide icons. README uses the standard License and credits
section; AGENTS.md/CLAUDE.md point to the licence and brand files.
