Add r (pole) and gain sliders with force r/gain checkbox in Synthesis
panel, visible when Resonator (all) is active. Restrict r range to
[0.75, 0.9999] for both global and per-partial sliders.
handoff(Claude): global resonator r/gain override controls added

Each partial in the Synth tab now has a Sinusoid/Resonator toggle.
Resonator path: y[n] = 2r·cos(ω₀)·y1 − r²·y2 + A(t)·√(1−r²)·noise,
coefficients recomputed per-sample from the freq Bezier curve.
gainNorm=√(1−r²) normalises steady-state power; gainComp for trim.
UI: mode toggle buttons, r + gain jog sliders, RES badge in header.
Docs updated in tools/mq_editor/README.md.
handoff(Claude): resonator mode complete, coefficients translated from
spread params in README, ready for perceptual comparison testing.

- Map 'E' key to Extract Partials
- Move extractBtn inline style to CSS rule #extractBtn
- Hoist autoSpreadAllBtn DOM ref to top with other refs
- Drop unused PADY local var in _renderAmpEditor
- Remove redundant comment before extractBtn listener
- README: add E/Esc keys, add editor.js to architecture, mark Phase 3 done
handoff(Gemini): mq_editor UX polish + doc consolidated

panel refresh after extract
- Clear extractedPartials and editor state when loading a new WAV
- After extract, refresh right panels (re-select if index still valid)
- Synth fields (decay, jitter, spread) get jog sliders: drag to nudge, spring-back on release
- Spread extension limit dashed line: alpha 0.4→0.75, lineWidth 1→1.5, dash [3,4]→[4,3]
handoff(Gemini): mq_editor UX polish — jog sliders, WAV reset, panel refresh, spread line visibility

- autodetectSpread(): measures half-power (-3dB) peak width in spectrogram
to infer spread_above/below (replaces near-zero bezier residual approach)
- 'Auto' button per partial + 'Auto Spread All' toolbar button
- Spread panel inputs now trigger viewer refresh on change
- 50% drop-off dotted reference lines on spread band (selected partial only)
- Mini-spectrum: use max() instead of mean() over bins per pixel column,
fixing high-frequency amplitude mismatch between original and synthesis
handoff(Gemini): spread autodetection and mini-spectrum fixes done

- Freq/Amp curve params now in tabs to save vertical space
- Add Synth tab: per-partial decay, jitter, spread_above/below controls
- Visualize spread band on selected partial (filled band + dashed bounds)
- Larger fonts and right panel (14px body, 260px panel width)
- Non-kept partials at 0.12 alpha (was 0.5)
- Default threshold -20dB (was -60dB)
handoff(Claude): mq_editor UI/UX improvements

- Click-to-select partials on canvas (proximity hit test on bezier)
- Right panel: peak freq/amp, time range, freq/amp bezier text inputs, mute/delete
- Selected partial renders on top with glow + larger control points
- Draggable freq curve control points on main canvas (grab/grabbing cursor)
- Amplitude bezier editor: 120px canvas below spectrogram, time-synced
with main view zoom/scroll via viewer.onRender callback
- Amp edits live-affect synthesis (mq_synth.js already uses ampCurve)
- PartialEditor class in editor.js owns all editing logic; index.html
wires it with 5 calls (setViewer, setPartials, onPartialSelect, onRender,
onPartialDeleted)
handoff(Gemini): partial editing MVP complete. Next: freq curve drag polish
or export (.spec generation).
