/* customer-grid/gridChat.css — the docked chat panel (W37-T40, contract C8).
 *
 * ⛔ MODULE-LOCAL BY CONTRACT, not by preference. C8 hands `index.css` (12k+ lines) to lane A
 * alone this wave, and every other lane adds styles in its own per-surface sheet imported by its
 * own component. The precedent already exists next door in `scriptView.css` and `navExtras.css`.
 * ⚠ Colours come from the design tokens (navy #1F4E78 + gold #C8A24B, DESIGN.md), never from fresh
 * hexes: a surface that invents its own palette is the thing the constitution exists to prevent.
 * Only the tokens this file actually uses are named.
 * ⛔⛔ NO FALLBACK LITERAL INSIDE A `font:` SHORTHAND, and this sheet shipped ten of them before
 * `web_ui` said so (lane A, mailbox A-47). A fallback there is a SECOND SOURCE OF TRUTH for a size
 * that silently becomes THE size the day the token is renamed, and `index.css` always loads, so it
 * can never actually fire. Sizes are therefore `var(--lp-fs-xs)` bare; colours keep their fallback
 * because a missing colour is a legibility failure rather than a silent wrong number.
 * ⚠ NO EMOJIS AND NO ALL-CAPS CHROME (DESIGN.md). */
