/* Advanced /proxies filter components (built by proxies.js).

 * Flat, accent-agnostic, 0 radius, 1px hairline borders — matches the rest of
 * the site. Colors come only from CSS vars so every accent theme works. The
 * popovers use a solid background + hairline border (no drop shadow) to stay
 * flat on dark while still reading as a layer above the table. */

/* Page-scoped overrides: this stylesheet only loads on /proxies. The proxies
   hero intentionally uses the same padding as the prompts/pricing/tools heroes

   .proxies-section below, not from a different hero. */
