/* Substack-style centered search overlay. Hidden by default; opened by `.search-trigger` clicks
   handled in `search-overlay.js`. Panel sits near the top so results appear naturally below the
   query input as the user types. Pagefind's `excerpt` HTML wraps matched keywords in `<mark>`
   tags — we colorize those red for the highlighted-keyword effect.

   Single source of truth for the search overlay's styling. Loaded via `<link rel="stylesheet">`
   from both the Astro playbook layouts (Layout.astro, HomeLayout.astro) and the Phoenix root
   layout (root.html.heex), so the home page and the playbook share one CSS file. Uses only plain
   CSS (`var()`, `color-mix(in oklch, …)`) — no Tailwind directives — so it can ship from
   `playbook/public/` as-is without compilation. */
