/* ──────────────────────────────────────────────
   SIA Icon Box — frontend
   Single-layout card with top icon, title, description, checkmark list.
   Three widget contexts share the .sia-ib root: single Card, Grid (.sia-ibg),
   Carousel (.sia-ibc).

   Anti-illusion conventions applied (per global SIA design system rules):
   - Universal `::after` 1px inner outline (Rule 6) for edge definition
   - `clip-path` for transform-stable rounded clipping (Rule 7) — emitted
     by the `ib_card_radius` Elementor control alongside border-radius
   - GPU layer hints on hover-animated elements (Rule 4)

   z-index: 5 puts the (transparent) link above ALL content layers (icon z:2,

   (font-size 0, no bg) but it's the topmost element in click hit-testing
   over the entire card surface — so a click ANYWHERE inside the card
   navigates to the link's href, not just the empty space between elements.
   The decorative ::after outline (z:10) sits above the link visually but
   has pointer-events:none so clicks pass through to the link beneath. */
