/**
 * Connected control bar that bridges `devicesContext` and `callStateContext`
 * to the pure `sw-ui-control-bar` UI component.
 *
 * Input precedence (most specific wins): `.call` > context.
 * When `.call` is set, the control bar drives screen-share / hand-raise /
 * hang-up directly from the Call. Mic/camera/speaker toggles still require
 * `devicesContext` — without it those buttons render in their default state.
 *
 * @prop {Call}    call             - explicit Call object (overrides context)
 * @prop {boolean} showScreenShare  - show the screen-share button
 * @prop {boolean} showHandRaise   - show the hand-raise button
 * @prop {boolean} showTranscript  - show the transcript toggle button
 * @prop {boolean} transcriptActive - current transcript panel visibility
 *
 * @fires sw-call-hangup - Re-dispatched when the user clicks hang-up so external
 *                         consumers (e.g. React parents) can react. No detail.
