 * InterGlobal Blog Stylesheet — FLAW #13 fix.
 * Self-hosted replacement for the runtime Tailwind CDN. Ships only the
 * utilities + components actually used by /blog/_TEMPLATE_V3.html so the
 * blog can hit Lighthouse ≥95/90/90 without runtime JIT compilation.
 * --------------------------------------------------------------------
 * Sections:
 *   1. Tokens + base
 *   2. Typography helpers
 *   3. Layout utilities (grid, flex, spacing)
 *   4. Color utilities (bg, text, border)
 *   5. Components (nav, blog content, TL;DR, FAQ, lead magnet, etc.)
 *   6. Responsive overrides (md/lg breakpoints)
