Stream 9 (part 1/2) — shared infrastructure for the per-mode TSX layer.
- ModeShell.tsx: common chrome (header, voice-space PillToggle, audio
start/stop, control axes, training controls, drawer, status line).
Modes only have to author primary input + output JSX.
- mode-runtime.ts: useModeRuntime(schema) hook. Owns input pipeline,
WASM ML calls, output pipeline, and a 50ms-throttled engine-host
bridge. Exposes setInput/processedOutputs/training/audio surfaces
so mode TSX stays declarative.
- mode-helpers.ts: schema → SliderBank config + Float32Array →
slider-range value mapping. Pure functions.
- ModeSwitcher.tsx: top-of-page <select> wired to modeStore.
ModeShell and the runtime read controlStore (Boldness/Memory/Precision)
to derive learning rate + RL noise cap so axes affect training without
needing per-mode plumbing.
