/**
 * Multi-line voice-input status panel.
 *
 * Renders the live state of a `voicetools serve` capture across its phases so
 * the user always sees what's happening:
 *
 * ```text
 *  ● Listening · 0:03                                    esc cancel
 *  ▁▂▃▅▇▆▄▂▁▂▄▆▇▅▃▂▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁    ← level history, left-anchored on a track
 *  › and so my fellow ameri▏           ← live partial transcript (PARTIAL)
 * ```
 *
 * Phases:
 *  - `warming`      spinner while the binary resolves / model loads; shows a
 *                   real progress bar when a download reports byte counts
 *  - `listening`    recording dot + elapsed timer + waveform + partial text
 *  - `silence`      trailing-silence countdown; waveform dims
 *  - `transcribing` spinner while the final decode runs
 *
 * The component self-animates (spinner, timer, countdown) on an internal timer
 * and calls `ui.requestRender()`; the owner feeds it protocol events via
 * `pushLevel` / `setPartial` / `beginSilence` / `setDownloadProgress` etc. and
 * disposes it on collapse.
