/**
 * Call Status Component
 *
 * Displays current call state with status text and duration timer.
 *
 * Input precedence (most specific wins): `.call` > context.
 *
 * @example
 * ```html
 * <!-- Inside a context provider: -->
 * <sw-call-status></sw-call-status>
 *
 * <!-- Standalone with an explicit Call: -->
 * <sw-call-status .call=${call}></sw-call-status>
 * ```
 *
 * @csspart container   - Outer status container.
 * @csspart status-text - Text label of the current status.
 * @csspart duration    - Elapsed-time label (only rendered when connected).
