/* Adinvenco — homepage offer band ($500 entry beside the tier ladder).
 *
 * Loaded ONLY from index.html, via the generator's extra_head hook. No other
 * page links this file, so no other page can be affected by it.
 *
 * Token system is the measured one from review/2026-10-21-DESIGN-SPEC.md §3:
 *   warm-black base #0B0B0C   surface #111113   card #161618
 *   hairline rgba(255,255,255,.08) / rgba(255,255,255,.16)
 *   ink #F2F1EE (16.0:1 on card)   secondary #A6A5A1 (7.3:1)   accent #E3B15F (9.2:1)
 *
 * Scoped rules only. The rest of the homepage keeps the site's existing
 * stylesheet untouched.
 *
 * Amber does exactly three jobs here, per the spec: the eyebrow rule, the
 * primary CTA fill, and the focus ring. Never decoration.
 *
 * Type scale follows the spec steps: 12 / 14 / 16 / 18 / 20 / 24 / 48.
