/* ── Theme tokens (#581 white-label; #590 token overhaul) ─────────────────────
   ONE semantic token set drives every surface, line, text and accent colour.
   --brand* derive from the TENANT's primary colour (ThemeState.BrandStyleCss
   renders :root + .theme-dark overrides after this sheet); light/dark flips via
   .theme-dark on the app shell wrapper. RULES: chrome + kit + component classes
   use tokens ONLY — no raw surface/text/line hex anywhere below (the splash is
   the one exception: it paints before the tenant brand loads). Pages may keep
   Tailwind slate/semantic utilities — the bridge at the end of this block
   re-skins the ones in real use (see the census in #590). */
