/* =============================================================================
 * kc-landing-skin.css — ONE DESIGN LANGUAGE ACROSS THE PLATFORM
 * =============================================================================
 *
 * The landing page (index.html, landing-2026.css) is the reference. This file
 * carries its chrome and components — the sticky glass nav, the wordmark, the
 * one gradient action, chips, inputs, cards, the eyebrow and the heading
 * scale — as `ks-` classes any page can wear (founder, 2026-09-13: "make the
 * rest of the entire platform look the same": the two-minute test, the
 * member door, the gate, the Knowledge Center, the account page).
 *
 * LOAD ORDER. After kc-theme.css and kc-uplift.css, before the page's own
 * sheet. Colours are read from the platform's LIVE tokens (--page, --plate,
 * --ink1..3, --acc, --grad, --on-grad from kc-uplift.css), with the landing's
 * hex as the fallback, so a member who has chosen the light ground keeps it
 * and everything else still matches. Fonts come from kc-theme.css, which now
 * names Comfortaa and Nunito in every register but clear.
 *
 * NOTHING HERE IS !important. The token layers keep theirs; this is a
 * component sheet and loses to any page rule of equal specificity written
 * after it, which is what a page-specific exception should look like.
 *
 * Contrast: every ink/ground pairing used here is a token pairing the audit
 * (node tools/contrast_audit.mjs) already measures; the literals below are the
 * landing's own, all passing on both grounds at their sizes.
 * ========================================================================== */
