- tts.worker.js: rewrite synthesis to the F5-TTS zero-shot layout
(cond = ref mel + zero tail, x = whole-length noise, text_ids =
ref+gen, slice gen frames after the flow) and RMS-normalize the
PCM to 0.1; fixes unintelligible output on both backends.
- New gemma-style UI (index.html/app.js), self-hosted fonts,
coi-serviceworker, trimmed ort runtime (ort.mjs + jsep pair).
- Load fp16 dit/vocoder graphs on WebGPU (int8 wasm fallback).
- README: accurate download sizes and fallback note.
