/* ── Showcase element: content paths ──
   Three-card row (Listen / Practice / Idioms) for [pp_showcase_paths],
   inviting a front-page visitor into each CPT's archive. Card tints are the
   documented --pp-card-bg-* tokens (STYLING.md "any card surface representing
   a specific CPT must use the --pp-card-bg-* token"); icons are the SAME
   markup archive-cards.php already uses for these CPTs, injected server-side
   — nothing here re-authors them. The whole card is the link (better tap
   target than a separate button, and only one thing to tab to); the
   "Explore" cue is inert markup riding inside that one link, never a second
   focusable element. */
