 * - Banner appearance on first visit
 * - EWR-Only toggle
 * - "Alle akzeptieren" saves consent and closes banner
 * - Consent persistence across reloads
 * - "Nur notwendige Cookies" saves minimal consent
 * - Cookie FAB button after consent
 * - FAB reopens banner with previous settings
 * - "Consent zuruecksetzen" resets everything
 * - API debug panel
 * - Category toggles (necessary is disabled)
