     .wp-block-cover__inner-container { z-index: 1 }

   which computes to (0,6,1) -- the :not() and :has() arguments each add to the
   count. The label therefore sits at z-index 1, the same as ::after, and ::after
   paints later, so it lands on top. The `z-index:2` that sat in
   impervora-category-tiles.php never won this either; it was dead the whole
   time. A plain-class override cannot beat (0,6,1), so the only routes are
   !important or an equally baroque selector -- both disproportionate for a 16%
   veil over white text, which reads as the intended warm wash. Left as-is so
   hover appearance is unchanged from before the consolidation. */

   below to 96px for header clearance; the 24px here is the no-JS fallback

   Scoped to `:has(:target)` rather than a bare `html { scroll-behavior:smooth }`
   ON PURPOSE. The global form inflates measured CLS badly: an auditing tool (or
   any script) that scrolls the document programmatically triggers the smooth
   animation, and the in-flight scroll offset is recorded as layout movement --
   it took desktop CLS from 0.002 to 0.36 here. `:has(:target)` arms smooth
   scrolling only once a same-page #anchor is actually active, so normal loads
   and full-page scrolls stay instant and shift-free. Degrades to instant jumps
   with no JS and self-disables under reduced motion. */
