/* ============================================================
   §09 100x — STOREFRONT HUB EXEMPLAR.
   The author's all-products hub at /@handle, rebuilt to the same
   craft bar as the §100x sales page (sales100x.css) but with a
   DISTINCT purpose: showcase + discovery across every published
   product, in the brand's NEUTRAL house identity (warm paper,
   clay accent, ink-on-cream, pixel / crop-mark / dot-grid
   blueprint motifs, Hanken Grotesk 800 display, Spectral serif,
   Spline Sans Mono small-caps eyebrows).

   The page chrome stays house-neutral because it aggregates
   products of mixed themes (spec 09 decision). Each product card
   *hints* its own theme accent via the inline --card-accent /
   --card-accent-deep vars, so the catalogue feels alive without
   the chrome inheriting any one theme. No new aesthetic — same
   tokens & motifs as the sales page, expressed as a hub.

   Outer wrapper keeps the existing `.store` / `.store__name` /
   `.shopcard` class hooks (public-routes test contract). New
   craft lives under the `.store--100x` modifier and `.sf*` names.
