/**
 * Opens the full-screen voice conversation (BOFF-7120).
 *
 * ★ It occupies the SEND button's slot, and only while the composer is empty —
 * which is both what Gemini does and the only thing that fits. The composer row
 * is exactly full at 390px (measured: attach 22-58, textarea 66-228, language
 * chip 236-280, mic 288-324, send 332-368), so adding a sixth control would push
 * send off the edge — the precise bug fixed in #293. Swapping rather than adding
 * costs zero width.
 *
 * There is no ambiguity in the swap: with nothing typed there is nothing to
 * send, so the send button was inert anyway. As soon as the user types, send
 * comes back.
 *
 * Distinct from the existing mic button, which dictates INTO the composer. This
 * starts a hands-free conversation and leaves the composer behind.
