// ── CalDAV Settings + Calendar Config ──
//
// Genuinely CalDAV-scoped concerns only:
//   * Settings panel (connection URL / user / password, Test + Save)
//   * Per-calendar color/icon configuration (persisted in localStorage)
//
// Sync orchestration (triggerSync, background poll, autosync toggle,
// sync-interval, relay settings, sync.tick hook) lives in sync.js.
