38- **Synthesize** — convert text to audio via local Piper TTS (ONNX model
39 loaded in-process via `piper-rs`). No external fallback. Output is f32 PCM
40 at the model's native sample rate (typically 22050 Hz mono), resampled to
41 48 kHz stereo via inline linear interpolation before playback. Songbird does
42 not resample — playing un-resampled audio results in wrong playback speed.
43- **TtsState** — struct held in poise `Data`: `OnceCell<Mutex<Piper>>` for the
44 model instance, `DashMap<String, (Vec<u8>, Instant)>` for the text→audio cache.
45 Piper loaded lazily on first TTS call. Cache keyed by full phrase string,
46 evicted by TTL. No Google TTS fallback.
47- **Pre-generation** — on first voice event for a user, synthesize all 6 event
48 phrases (join/leave/deafen/undeafen/mute/unmute) with their display name and
49 cache them. ~120ms first time, instant after. Lazy — no startup cost.
