/* ============================================================
   FORGE — Blog. Shares the landing's token system (one variable
   set, two skins) so /blog reads as the same product. Linked by
   the hub (/blog/) and every post.
   Layout grammar:
     • hub = two-column masthead (headline + cover story), a
       prominent space-filling series nav, and each series an
       editorial, collapsible index list (no eyebrow-per-section)
     • post asides (callout / hook / details / quote) are
       full-bordered blocks / a hanging pullquote — no side stripes
     • posts carry a reading-progress bar (js/forge-blog-progress.js)
   Keep tokens in sync with the inline set in index.html if changed.
