/* ClaimCure Business Portal — Design Token Layer
 *
 * Source: ops/gemini_design_tokens_2026-05-06.css (color/font kernel) +
 *         claimcure_business_design_assets.md §2 (full token spec, 2026-05-03).
 *
 * Light-mode-only by intent. The Gemini brief explicitly drops dark mode for
 * the business portal because the consumer/business consumer needs differ:
 * pros want density and consistency, not aesthetic novelty. Dark-mode classes
 * in inheriting templates render fine but are no-ops here.
 *
 * Layered with Tailwind utility classes — these tokens provide CSS variables
 * for things Tailwind can't express cleanly (semantic status colors used in
 * status badges, font-face rules for self-hosted Inter).

/* ============ Self-hosted Inter (variable axis 100-900) ============
 * Vendored at web/static/fonts/. Eliminates referer leak to fonts.gstatic.com
 * on every page. SecurityHeadersMiddleware adds strict-origin Referrer-Policy
 * as belt-and-suspenders; this self-host is the underlying fix.
