/**
 * MultiSelect – styly komponenty.
 *
 * Převzato z FCT (app/public/assets/css/multi-select.css, řádky 1–262, commit 325b609).
 * Změny proti FCT:
 *  - pevné barvy (#fff, #dee2e6, #6c757d…) nahrazené proměnnými Bootstrapu 5.3,
 *    takže komponenta sama funguje i v [data-bs-theme="dark"];
 *  - firemní barva z tokenů gateway (fragile.css): výplně --primary,
 *    text/ikony/obrysy --primary-fg (v tmavém režimu drží kontrast);
 *    mimo gateway padá na pevné #3830a3 a proměnné Bootstrapu;
 *  - písmo se dědí z body (Inter už načítá layout);
 *  - viditelný fokus pro klávesnici (:focus-visible);
 *  - vynechané styly filtračního panelu a toolbaru pohledů, patří jen FCT.
