/* ============================================================================
   CrewSync v2 Design System — Navy primary + Coral accent
   Stripe / Linear-grade enterprise overlay.

   CASCADE STRATEGY
     This file is linked AFTER the inline <style> block and crewsync-ds.css.
     Every selector uses the `rc-*` prefix (or `--rc-*` for variables), so it
     never collides with the legacy --itl-*, --brand, or --cs-* namespaces.
     Existing pages keep their look until a caller opts in by adding an
     `rc-*` class. The only global surface change is the page background
     applied to `body` (light slate) — see safety note below.

   SAFETY CONTRACT
     - Zero forced visual change to existing markup.
     - No mass renames (.badge-amber → rc-badge-warning happens post-demo).
     - No replacement of the working service worker.
     - No layout rewrite (existing .app-body / .sidebar / .content untouched).
