/* alignalgo-front/articles/articles.css
   Shared stylesheet for the Movement article pages — reuses the exact tokens,
   fonts, header/nav, and footer treatment from ../index.html so these pages
   read as the same site, not a bolted-on blog. Self-hosted fonts only, no
   CDN, no build step — same "dependency-free static HTML" posture as the
   rest of alignalgo-front. Keep in sync with ../index.html if its tokens
   change (--cream/--sand/--stone/--ink/--gold and the font stack are the
   ones that matter most). */
