/* ============================================================
   Frame blog — shared stylesheet
   ============================================================
   ONE file for every blog page, in every locale. Article HTML
   carries content only; nothing here may be duplicated inline.

   Layout: sticky anchor-TOC left / body centre / quick-answer +
   internal links right. Both margins carry real, crawlable HTML.

   Hard rules (see .claude/skills/frame-blog/SKILL.md):
   - The TOC must be complete in the HTML. JS may decorate it,
     never build it: GPTBot/ClaudeBot/PerplexityBot read raw HTML
     and do not execute JS, and Google mines in-page anchors for
     "Jump to" sitelinks.
   - Body text ≥ 4.5:1 contrast; house target 7:1.
   - --amber is 3.39:1 on paper: ACCENT ONLY, never text.
   ============================================================ */
