   g3-core.css — the shared design foundation (UI redesign Phase 1)

   One token set + one component kit for the staff dash, member portal,
   public site and kiosks. Approved at the Phase 1 design checkpoint
   (Figma "G3 Dash — Phase 1 Design Foundation", 2026-09-27).

   HOW IT LOADS
   Linked BEFORE g3.css (staff) and g3-mobile.css (portal). Those older
   sheets still win wherever a name collides (the --accent* family, which
   already means the same thing), and every class here is prefixed ui-, so
   existing pages keep their look. One deliberate side effect: a few staff
   partials that already read portal-style names with light-only
   fallbacks (var(--text, #1F2933) in interns/_snapshot_body.html,
   _storage_file_preview.html, admin/server_env.html) now get proper
   dark-mode values instead of light colors on a dark page. Pages adopt
   the kit as each redesign phase touches them; the living reference is
   /admin/ui.

   RULES
   - Classes are prefixed `ui-`. Never style a `ui-` class from a page.
   - No hex colors outside this token block. Components use tokens only.
   - Every component defines its own narrow-screen behavior here, once.
   - Status colors come from core/status_tones.py via the pill macro.
