/* ───────────────────────────────────────────────────────────────────────────
   groovemark.app — the shared site stylesheet (2026-09-16, the site rebuild).
   ONE copy of the tokens, the base, the header and the footer for every page
   (index, groovemark, gp-33, help + its articles, privacy, terms). Page-specific
   rules stay inline in each page. Tokens are copied from static/style.css :root
   — never retyped from memory (style-guide § 2).
   The header is the apps' own (Derek, 2026-09-15): the groove-maze mark + the
   GROOVEMARK wordmark upper-left, Help / GMK-1 / GP-33 upper-right beside the
   handle. The mark's path is copied from static/index.html's .brand-mark
   (canonical: ~/grooveplay/assets/gmk-mark.svg).
