/* =====================================================================
 * Stage — public showcase / template browse page (/stage, /templates)
 *
 * Editorial gallery layout. Apple Newsroom + magazine-cover inspired.
 *
 *   • Compact hero — eyebrow + tight headline + tagline. The featured
 *     mosaic below is the visual centrepiece, not the title bar.
 *   • Featured mosaic — 1 hero card + 3 companions on desktop.
 *   • Sticky toolbar — category pills + search. Sort row sits below.
 *   • Image-only cards — hover reveals title + author + Use-template CTA
 *     over a gradient scrim. On touch devices (no hover) the meta is
 *     always visible underneath the image, per Editorial Gallery spec.
 *
 * All tokens come from variables.css (DESIGN.md §2). One iridescent
 * moment per surface lives on the wordmark span. Hairlines use the
 * canonical rgba(text, 0.06 ~ 0.5) pattern.
