/* ── GaaS Docs — Shared footer ────────────────────────────────────────────
 *
 * Linked by EVERY page in docs/public/, immediately after that page's inline
 * <style> block so these rules win the cascade.
 *
 * Ported from the gaas.is footer (marketing site) and fully de-tokenized:
 * docs/public defines no :root and no custom properties, so an inherited
 * var() would silently resolve to `unset` — and an invalid var() inside a
 * `background` shorthand kills the whole declaration. Every value here is a
 * literal. Do not reintroduce var().
 *
 * Colors are AA-checked against the page background #0a0e17:
 *   #8b949e  6.27:1  PASS  (resting text and links)
 *   #c9d1d9 12.50:1  PASS  (hover)
 * The old footer color #484f58 was 2.33:1 and is deliberately not used here.
 * ------------------------------------------------------------------------ */
