/**
 * Per-participant control panel.
 *
 * Takes a `participant-id` and looks up the participant.
 * Shows mute audio, mute video, volume, pin, and remove actions based on
 * the `capabilities` list from the call state.
 *
 * Input precedence (most specific wins): `.call` > context.
 *
 * @prop {string} participantId - ID of the participant to control
 * @prop {Call}    call         - explicit Call object (overrides context)
 * @prop {boolean} showVolume   - show volume slider
 * @prop {boolean} showPin      - show pin/spotlight button
 *
 * @fires sw-participant-volume-change - Volume slider changed. Detail: `{ participantId: string, volume: number }`.
 * @fires sw-participant-pin-toggle    - Pin/unpin clicked. Detail: `{ participantId: string, pinned: boolean }`.
 *
 * Themed via the SignalWire DTCG tokens (`--bg-page`, `--bg-surface`, `--bg-surface-raised`,
 * `--fg-default`, `--border-default`, `--radius-md`, `--shadow-md`, `--type-family-body`,
 * `--type-size-small`, `--interactive-button-destructive-bg`,
 * `--interactive-button-destructive-hover`, `--transition-fast`).
