/* chat-brand.css — the chat page wears the app's colours (docs/APP_FLAGSHIP_PLAN.md پ۶).
 * Only when <html data-nbg-brand> (key chat_brand in live/app_mode.json; false ⇒ today, byte for byte:
 * every colour literal in the chat CSS is var(--nbgc-<hex>, <the same literal>) / rgba(var(--nbgr-r-g-b, r, g, b), a)).
 * Every value below is a token of platform-home.css / tutor-grade-hub.css — no new colour.
 * Map: each navy / slate / blue / teal / green literal ⇒ the brand token nearest in luminance (neutral ⇒ warm
 * black-and-cream, accent ⇒ the app's action green); the chat's own tokens are set by hand. Generated once by
 * the s1 session (scratchpad brandify.js); a new literal in the chat CSS should use these tokens directly. */
