/* ---- Breadcrumb ---- */

/* Structural merge (2026-08-16, Track B): breadcrumb moved inside
   .da-hero--compact (see dataartha.css), so it shares one box and one
   continuous 135deg gradient with the hero — no separate background to
   keep in sync. Two prior attempts (flat navy-700, then a copied gradient
   on the separate box) both failed under computed math — see
   docs/known-issues.md for the full write-up. .da-hero--compact's
   padding-top now absorbs the fixed-nav clearance this rule used to
   provide alone; this rule's own margin-bottom preserves the prior visual
   gap before the H1 row. */
