/* ==========================================================================
   UniFluent — blog article pages
   --------------------------------------------------------------------------
   Shared by every blog post and its locale clones; replaces the per-file
   inline <style> blocks (extracted 2026-08, restyled to the dark brand).
   Load order: brand.css first (tokens, navbar, footer, base), then this.

   Anatomy: breadcrumb strip → article header (dark, indigo glow) →
   hero image → reading column → boxes (toc/tip/stage) → inline CTA →
   related articles band → page CTA. Footer and navbar come from brand.css.

   Notes for the port:
   - Body copy is deliberately brighter than --uf-text-dim: long-form
     reading needs more contrast than UI chrome.
   - Logical properties (margin-inline, border-inline-start) keep the
     Arabic (dir="rtl") clones correct without their own rules.
   - Breakpoint is 900px to agree with the navbar collapse in brand.css;
     768 (the old inline value) left iPads in a hybrid state.
