/* ==========================================================================
   fontcurator-blog.css — the BLOG SUBSYSTEM style overlay
   docs/specs/fontcurator-blog-20260604.md v0.3 §4a

   Boundary rules (the reason this file is allowed to exist as the third
   project stylesheet):

     - Loaded ONLY on /blog, /blog/{category}, /blog/{category}/{slug} and
       the admin draft preview — via Layout::BLOG_CSS, chained by the three
       blog page classes. Layout::page() does NOT load it, so no other
       public page gains a byte.
     - Loaded AFTER fontcurator.css, so it inherits every brand token
       (--bs-primary Copper, --bs-dark Charcoal, --bs-body-bg Cream, the
       Helvetica Neue / Georgia split) and overrides nothing global.
     - EVERY rule is namespaced under `.fc-blog`. Brand tokens flow in;
       nothing flows out. Blog styling can never leak to the rest of the
       public site.
     - fontcurator.css stays brand-frozen and is not edited by the blog.
       If the blog needs a brand token that doesn't exist, that is a brand
       sign-off conversation, not a blog commit.

   Nothing here is shared with fontcurator-admin.css — the admin breadcrumb
   is a separate component in a separate overlay that must never reach the
   public site.
