/* MAR AI LLC — house stylesheet.
 *
 * Palette is not invented. Every colour below sits on the hue axis measured
 * out of the LUMAI app icon itself (H 214–226 across the whole artwork, near-
 * black ground, electric blue structure). The accent is that same hue pushed
 * to full chroma. Nothing here is warm; nothing here is decorative.
 *
 * Constraints that are deliberate, not laziness:
 *   - Fonts are self-hosted (fonts/). A company that tells people it does not
 *     track them cannot pull a stylesheet from someone else's CDN on load.
 *   - No build step, no script, no cookie, no third-party request of any kind.
 *   - One stylesheet for every page and every company in the family. Change a
 *     token here and the whole house moves.

/* ---------- faces ---------- */
/* Both files are true variable fonts, so one request covers every weight the
 * page uses. Do not swap in static cuts — that is four requests for less range.
