Andrew FrahnandClaude Opus 5.5 6cbc0eb5a9 Phase 0: configurable brand, MIT licence, plan/ and Immich tracker
- 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

# Regenerate every app icon file from brand.toml's icon_svg (brand/icon.svg), into assets/app-icon/
# under neutral names (app.ico, app.icns, app-1024.png, app-macos-512.png, hicolor/<size>/apps/app.png).
# Packaging renames the hicolor icons to the brand's app id (packaging/env.sh install_icons).

# Needs: resvg (brew install resvg / cargo install resvg). On macOS, iconutil also writes the
# .icns. The outputs are committed, so building and packaging never need these tools.
