/* MOP-766 — chatbot search-link CTAs.

   All brand colors reference the per-portal CSS custom properties set by
   PxUserStyleGeneratorService (--wp--preset--color--primary and the
   generated -10/-20/-30/-40 shades). Alpha tints use relative color
   syntax `rgb(from <var> r g b / <alpha>)`, already established in the
   platform theme's base.css.

   Explicit resets (not `all: revert` — that re-inherits buttonface system
   colors) plus `!important` on no-paint declarations so global theme button
   rules can't bleed in on hover/focus/active. */

/* Stacking-context fix: AOS animations apply `transform` to block wrappers
   (`.custom-container`), turning each block into its own stacking context
   regardless of z-index. On the homepage the popular-posts wrapper sits
   after the search-box wrapper in DOM order, so without an explicit
   z-index it paints over our dropdown. `:has()` keeps the selector
   self-contained — only the block hosting the link is elevated. */
