/* ─────────────────────────────────────────────────────────────────────
   AVENU — bestseller-grid
   Section head: left = eyebrow chip + h2 ("Bestsellers", Space Grotesk
   display 36px desktop); right = inline row of category sub-tabs (All /
   Men / Women / Footwear), active tab has a 1px black underline. To the
   far right, the "View all →" link (with arrow icon).

   Body uses the shared `.product-grid` from common.css (4-up desktop,
   3-up tablet, 2-up mobile). Cards are rendered by the product-card
   snippet — this stylesheet only owns the head + the placeholder shell.

   Responsive at 1440 / 768 / 375. On mobile the tab row scrolls
   horizontally inside its own track so the section head stays compact.
