/*
 * SDAweb Calendar Sync — ICS subscribe button + popover.
 *
 * Pattern:
 *   .sdaweb-gcal-ics                 — wrapper (relative anchor)
 *   .sdaweb-gcal-ics__button         — pill trigger
 *   .sdaweb-gcal-ics__popover        — anchored popover (desktop) / bottom sheet (mobile)
 *
 * Animation respects prefers-reduced-motion. Dark mode honors the display's
 * palette via existing CSS custom properties (no hard-coded greys).
