/**
 * Call Media Component
 *
 * Renders the remote video stream with aspect-ratio-aware sizing.
 *
 * Input precedence (most specific wins): `.stream` > `.call` > context.
 *
 * @example
 * ```html
 * <!-- Inside a context provider (sw-call-widget): -->
 * <sw-call-media></sw-call-media>
 *
 * <!-- With an explicit Call: -->
 * <sw-call-media .call=${call}></sw-call-media>
 *
 * <!-- With a raw remote stream: -->
 * <sw-call-media .stream=${remoteStream}></sw-call-media>
 * ```
 *
 * @csspart container - Outer container that holds the video and overlay layers.
 * @csspart video     - The `<video>` element rendering the remote stream.
 *
 * @slot - Default slot for overlay layers (e.g. `<sw-self-media>`, `<sw-participants>`).
