   GEXI — public/chat/v2/chat.css  (Chat v2, C2)
   A clean, premium, Gemini-grade conversational UI. Mobile-first, light/dark,

/* P2 — ONE DESIGN LANGUAGE. The assistant's tokens are now thin ALIASES onto the canonical brand
   :root (styles.css), via the proven frontdoor.css local-alias recipe (local-name: var(--brand)).
   All 131 in-file --cv-* references keep working — so app.js + markdown.js need ZERO change — but
   they now resolve to the gecko-green brand in BOTH light and dark: the brand tokens self-theme, so
   the old parallel `html[data-theme="dark"]` block is gone, and the off-brand blue→purple→pink
   --cv-grad is dead. styles.css MUST load before this file (it does — see chat.html). */
