/* KromeWeb — theme-agnostic base layer.
   Per-theme colour tokens, hero/collection/story/testimonial/CTA patterns, and the
   article-page opaque-header coupling live in per-theme sheets:
     - css/theme-fotokrome.css
     - css/theme-motion.css
   Which one applies is gated by the `.theme-{key}` class `WebLayout.razor` puts on `.kw-site`.

   Note on `.fk-*` names: `.fk-container`, `.fk-btn*`, `.fk-section*`, `.fk-section-title*`,
   and the `.fk-product*` grid primitives are SHARED across themes (MotionHeader + every
   CMS block component depend on them). The legacy `fk-` prefix is kept to avoid rippling
   a rename into seeded HTML + Blocks + Motion; treat them as design-system primitives,
   not Fotokrome-only. */
