/*
 * Duneed catalogue — the public product/family/category/brand pages
 * (plan 24 §6, phase 3).
 *
 * Layered ON TOP of blog/blog.css, never instead of it: that file owns the
 * design tokens (--color-*, --radius-*, the light/dark palettes) and the
 * shared shell (header, footer, .wrap, .pagination, .empty-state). This one
 * only adds the components the catalogue introduces, and every colour below
 * is a token reference — no hex values, so a palette change stays a
 * one-file change and dark mode keeps working for free.
 *
 * Loaded only on catalogue pages, via `blog/base.html`'s `extra_head` block:
 * a blog post has no reason to download it.
 *
 * Mobile-first throughout; the only breakpoint is 640px, matching
 * blog.css's. Every grid is `auto-fill`/`minmax`, so nothing needs a media
 * query to reflow, and every image slot has a reserved aspect ratio — plan
 * 24 §6 requires Core Web Vitals to pass on mobile, and layout shift is the
 * cheapest one to lose by accident.

   flex row — no extra wrapper element, and the chips keep wrapping exactly
   as they do everywhere else. */
