/*
 * baccalab landing page v1 — light only (Markos, widget 4 Oct 2026; Brief 62).
 *
 * Every value in :root below is copied VERBATIM from the portal's light palette,
 * apps/portal/src/styles.css:20-79, as it stood on 2026-10-04. That file is the
 * source of truth: no colour here is invented, and this page holds only the
 * tokens it actually uses. There is deliberately no dark-theme attribute selector
 * and no system-preference media query — the portal's dark palette is an explicit
 * toggle this page does not carry, so it renders the light palette always.
 *
 * Contrast was checked by computation, not by eye. Worst body-text pair is
 * --text-muted on --app-bg at 4.51:1; every body pair is >= 4.5:1. One pairing
 * was rejected by that check: --text-muted on --brand-soft measures 4.38:1, so
 * the "coming soon" label sits on a neutral chip rather than a brand-tinted one.
