Replace ad-hoc lime/forest-green system with the official 4-color HLC
palette. Lime + midnight are the primary pair; cyan + cream supporting.
Tokens
- :root now exposes --hlc-lime, --hlc-midnight, --hlc-cyan, --hlc-cream
plus channel-token siblings (--hlc-*-rgb) so tints can be expressed as
rgb(var(--hlc-*-rgb) / a) without hex literals.
- --color-bg → cream, --color-text/--color-hero-bg → midnight,
--color-accent → lime, --color-accent-dark → midnight (foreground on
lime; passes WCAG AA where #fff failed).
- New --sidebar-* tokens for the dark sidebar surface.
Sweep (frontend/src/styles/global.css)
- Replaced every hard-coded #c6f41c / #65a30d / #84cc16 / #b8e616 /
#4d7c0f / #1a2e1a / #1a1a2e / #1a2e05 with the matching var(...).
- rgba(101,163,13,a) and rgba(198,244,28,a) collapsed to
rgb(var(--hlc-lime-rgb) / a).
- text-on-lime now uses var(--color-accent-dark) instead of #fff;
btn-danger keeps white on red.
Sidebar reskin (cronus's audit, F-30)
- Background: midnight; text: cream (muted via cream-channel alpha);
active/hover: lime. Border + hover use cream-channel alphas so no
rgba hex creep on the dark surface.
Brand assets
- manifest.json theme_color → lime, background_color → cream.
- icon.svg / icon-maskable.svg base recoloured to lime + midnight glyph.
- 32× <meta name="theme-color"> across pages updated to #BFF355.
- Email templates (base.html, invitation.html) lime accent updated;
mail_service_test.go expectation tracks the new hex.
Deferred / out of scope
- PNG icons under public/icons/ are baked artefacts; regen left to the
next deploy.
- Categorical chip colours (office tints, traffic-light red/amber/green,
termin-type hues) are functional, not brand, and deliberately
untouched.
- Dark mode is not in scope.
Verified
- bun run build clean.
- go build ./... clean; mail render tests pass.
- Visual sweep at 1280×900 against frontend/dist via Playwright on
/, /login, /dashboard, /projects, /agenda, /team, /fristenrechner,
/glossary — sidebar midnight + lime active, cream page bg, white
cards, midnight text on lime CTAs.
Supersedes audit findings F-14, F-30, F-31.
