/* ═══════════════════════════════════════════════════════════════════════════════════════════════════
   BRANDS ARCHIVE — /brand/, from ~/Downloads/brands-archive-mockup.html, 22 Sep 2026.
   Scoped to `.pt-ba`. `.alphabet-filter` keeps its own class per the brief but is styled inside the
   wrapper, so the old `css/brand-page-styles.css` rules cannot reach these (they are (0,1,0), these are
   (0,2,0)) and the two sheets cannot fight.
   The mockup's `@container` queries become `@media` at 1100 and 640.
