/*
 * Burvic design tokens — the ONLY place raw values live.
 * Names are a contract shared by the marketing site, app.css (staff), portal.css and
 * chat.css; do not rename tokens. Primitive -> semantic. Components use semantic tokens only.
 * VALUES = the original burvic.com design (legacy/assets/css/burvic.src.css):
 *   ink #0F1733 / paper #FFFFFF / mist #EEF2FF / cobalt #2447F5 / sun #FFC916,
 *   Bricolage Grotesque (display) + Figtree (text), pill buttons, 16px cards, 10px inputs.
 * Restored 2026-10-22 (Client Projects/burvic/qa/theme-restore-site.md).
 * The marketing pages load burvic.css + elevate.css after this file; those define the
 * legacy component variables (--paper, --cobalt, --sun, ...) with the same values.
