Aspect-ratio-aware preview tile for the local camera, with a “camera off” placeholder when video is muted or the stream is missing.

Designed for small picture-in-picture-style previews — typically slotted into <sw-ui-call-layout>’s floating-video slot or used standalone in a settings panel. The element reads getSettings() on the active video track to detect the natural orientation (landscape, portrait, or square) and rewrites --sw-local-camera-aspect so its container hugs the track.

Input precedence (most specific wins): .stream / .videoMuted > .call > context. Any of .stream and .videoMuted can be set independently — for example, you can supply an explicit stream from a “join” preview screen while still letting videoMuted come from devicesContext.

The mirror attribute reflects to the host so it can be styled with :host([mirror]) and is the natural default for selfie cameras.
