/*
 * /site-redesign/_shared/styles/tokens.css
 *
 * Apex design tokens — UPDATED to the v1.3 system (2026-05-13 handoff bundle).
 * Variant in use: **LIGHT** — white surface, black ink, green single accent.
 * Strategic dark bands (mission on home, final-CTA on /intro, footer) use `.on-dark`.
 *
 * Two-layer token setup:
 *   1. Authoritative system names (--apex-*, --fg, --bg, --accent, --fs-*, --s1..--s8)
 *      — these are what new code should reference. Match the design-system handoff
 *      `colors_and_type.css` verbatim.
 *   2. Legacy bridge names (--color-*, --type-*, --space-*, --radius*)
 *      — the names pack-3's draft.css already uses. Point them at the new tokens
 *      so existing layout renders correct without per-file refactor.
 *
 * Fonts (Archivo Black + Inter) are loaded via <link> in head.html so they start
 * downloading before this stylesheet is parsed. No Adobe Fonts kit needed.
