/* ═══════════════════════════════════════════════════════════════════════════
   /pages/ + /pages/{slug}/ — "اخبار و مقالات". Page-scoped layer on top of the
   landing theme.

   WHY A SEPARATE FILE AND NOT PART OF index.css
   ---------------------------------------------
   `css/style.min.css` is a GENERATED bundle and the build script that produces
   it is not in this repo yet. Adding these rules to index.css would change a
   source the served bundle is NOT rebuilt from — the page would render
   unstyled with no error anywhere. Linked only on these routes by the
   `[@page->pagecss]` branch in biiq.views.main.v2head.html. Same reason
   about.css, crypto.css and home-prices.css exist; fold all four into index.css
   the day that build script lands.

   Everything here is ADDITIVE. Tokens, .glass, .section*/.divider/.reveal/
   .stagger-child and the .btn-* family come from the bundle and are reused
   as-is. Classes are `.pg-`-prefixed so a future merge cannot collide.

   --pg-accent is set per element by pages.js from a data-pg-accent attribute —
   never by a style="" attribute, because the frontend is CSP-clean. The
   fallback here is what renders if that script never runs, so every rule that
   uses it must look deliberate at the fallback value too.

   RTL: the document is dir="rtl". Directional values are LOGICAL properties
   (inset-inline-*, padding-inline-*, border-inline-*, margin-inline-*).
