/* ============================================================
   DUBUZ THEME SYSTEM — 4-Theme Semantic Token Layer (v2)
   ============================================================
   Vocabulary (shared web + API + Flutter):
     data-theme = red | blue | purple | dark   → the authoritative theme
     data-mode  = light / dark                 → legacy alias (maps onto dark theme)
     html.night-mode                            → legacy alias (maps onto dark theme)

   Dark is now a FULL THEME (data-theme="dark"), not a mode toggle.
   The old night-mode toggle and data-mode="dark" still work as compat
   aliases that resolve to the SAME dark token set.

   Load THIS FILE LAST (after mobile-layout-theme.css, design-system.css,
   alibaba-layout.css, account-dashboard.css, dubuz-theme-v2.css) so the
   token overrides below win and recolor every sng / dash / al component.

   Architecture (per .cursor/rules/dubuz-theme-system.mdc):
     COMPONENT → SEMANTIC TOKEN → THEME TOKEN → ACTUAL COLOR
