   WHITE OAK MEDIA — Client Portal
   10-design-system.css — REDESIGN OVERRIDE LAYER
   ────────────────────────────────────────────────────────────────────
   Authoritative design-system layer from the 2026-06 handoff. Loads LAST
   so it wins the cascade over 01–09 without editing them. Strategy:
   "override layer first" — instant, reversible visual lift; old rules are
   retired in a later cleanup phase.

   Faithful to the handoff: flat (no shadows anywhere), warm cream
   surfaces, navy-deep shells with an oak accent rail, Gilroy in three
   weights only (300 / 500 / 800), hierarchy from color + weight + space.

   Phase 0 — token foundation (canonical names + alias legacy --color-*)
   Phase 1 — shells + shared components
   To revert the whole redesign: remove the <link> to this file.
