/* ============================================================
   CREWLY ASCEND - GLOBAL THEME & BASE STYLES
   Version: 5.0 — Premium refresh + light/dark theming
   ------------------------------------------------------------
   Theming model:
   - :root defines brand constants + LIGHT theme semantic tokens.
   - html[data-theme="dark"] overrides the semantic tokens only.
   - Components must use semantic tokens (--surface-*, --text-*,
     --border-*) — never raw hex/rgba — so both themes work.
