- brand.toml is the only place the product name lives; every crate and app
reads it through dac-brand (env vars with legacy fallback, settings folder
with copy-only migration, default library, preset extensions, i18n {app})
- cargo xtask brand check|test, run|install|package, docs, rename-crates,
deny and immich; packaging files are templates rendered from brand.toml
- icons regenerated from brand/icon.svg; upstream branding removed
- MIT licence (segment and fetch stay Apache-2.0); cargo deny licence policy
- clean-room rules in AGENTS.md/CLAUDE.md; docs/upstream-merge.md
- plan/ rebuilt and committed; parity tracker reopens Classic rows, adds
PLAN.md section 2 rows and the IMM Immich section; plan/immich.md and a
pinned Immich test server
