/* ============================================================
   GLOBAL BOTTOM UTILITY BAR  ·  the "anti-header"
   Shared across every portfolio page. Depends only on tokens
   from css/hero.css (--mono, --cyan, --muted, --dim, --border,
   --text, --bg), so it can be dropped in right after hero.css.

   Adds three things and nothing else:
   1. .pf-ubar        slim fixed bar at the bottom of the viewport
   2. left group      controlled content scale  [ − 100% + ]
   3. right group     instant language switch   [ EN / IT ]

   Content scale is applied with `zoom` on the root element — the
   browser's own, layout-safe scaling path: sticky / fixed children
   keep working, the document height stays correct and the layout
   reflows to the scaled width (so a mild scale-up never adds a
   horizontal scrollbar). The bar counter-scales itself so its own
   UI always renders at 100%.
