 * home.css — Inquatra Landing 2.0 (UX 2.0 P1.2).
 *
 * ONE WORLD: this page consumes src/shell/tokens.css (--inq-*) directly —
 * the landing IS the product's visual world (Decision D1: one dark world,
 * yellow-led). The old light whitepaper lives on at /methodology with its
 * own landing.css; this file replaces it as the commercial front door.
 *
 * Token discipline: colors/radii/shadows come from --inq-* tokens; the only
 * local tokens are page-scale type sizes (marketing display scale — same
 * Inter family as the app, larger volume).
