/**
 * Shared program card grammar (one copy for every surface).
 *
 * The complete card, glimpse overlay, and detail dialog / bottom sheet system
 * plus the grid container tracks, extracted 2026-07-30 from programs.css,
 * dashboard.css (.dash__grid), and landing.css (.lp-btn family) so the public
 * landing grid and the /account Explore page consume the exact same rules.
 * Landing pages load this file in the old programs.css slot; the account app
 * links it from index.html after /design-tokens.css. Consumes only Tier 1/2
 * vars (--theme-*, --accent-*, --space-*, --radius-*, --motion-*, --text-*,
 * --weight-*, --tracking-*, --font-display, --font-body) so it themes itself
 * on any page that loads /platform.css and /design-tokens.css first.
 *
 * Interaction grammar ported from uruguide's business grid and the grid.bz
 * glimpse overlay: hover elevation and cover zoom on fine pointers only, a
 * first-tap glimpse on hoverless devices (is-glimpsed), a See more CTA that
 * opens the detail dialog, and a Material 3 bottom sheet variant with
 * drag-dismiss on narrow viewports. Markup is rendered by dashboard.js on the
 * landing and by pages/explore.tsx in the account app; both emit identical
 * class structure.
