feat(playground): implement Phases 2-4 of control surface spec
...
Phase 2 — Pinning + History:
- snapshot-stack.js: ring buffer (20 max) with auto-snapshot on
train/randomize/thumbs-down, multi-level undo, tagged entries
- ab-compare.js: A/B weight state comparison with capture/toggle/accept/revert
- region-pin.js: pin rectangular input-space regions (Approach A: example
pinning), pinned examples always included in training
- param-pin.js: per-output pin flags, pin mask skips pinned nodes in moveWeights
- phase2-ui.js: undo button with history popup, A/B toggle, long-press region
pin, double-tap param pin
- Modified mlp.js/iml.js/nisps-wasm.js to accept outputPinMask in moveWeights
Phase 3 — Input Refinement + Exploration:
- pressure-feedback.js: touch force + hold duration → intensity multiplier
- auto-explore.js: automated thumbs-down at configurable interval, zoom-scaled
- input-heatmap.js: 16×16 MLP sampling, 3 color modes (luminance/variance/
divergence), zoom-aware resampling, offscreen canvas rendering
- phase3-ui.js: auto-explore toggle with progress ring, heatmap eye icon,
pressure indicators, settings drawer section
- joy-map-enhanced.js: added setHeatmap() for background layer rendering
Phase 4 — Output Pipeline + Visualization + Polish:
- output-pipeline.js: global curve → smoothing → slew rate → freeze gate
- weight-health.js: weight magnitude histogram, dead/saturating/healthy status
- gradient-flow.js: per-layer weight-delta analysis, vanishing/exploding detection
- session-presets.js: save/load full state, URL sharing via compact params
- phase4-ui.js: freeze button, network health panel, session preset UI
All phases merged into a-app.js with proper integration: auto-snapshots,
pressure-modulated RL, heatmap triggers, output pipeline in routeOutputs,
gradient capture around training, persistence for all new state.

feat(playground): implement Phase 1 control surface — compound axes, input pipeline, enhanced joy-map
...
Three new standalone ES modules + integration into a-app.js:
- input-pipeline.js: 5-stage processing (deadzone → zoom → curve → smoothing →
momentum-as-zoom), 3 anchor modes, zoom-at-zero freeze, per-axis overrides
- control-surface.js: compound axes (Boldness/Memory/Precision) with interpolation
tables, offset-based override resolution (trim-pot model), 6 built-in presets
- control-surface-ui.js: floating bar axis sliders, gear icon settings drawer with
Input/Training/Exploration/Output sections, log-scale sliders, override dots
- joy-map-enhanced.js: zoom minimap with adaptive grid (4×4→32×32), vanishing trail
with Catmull-Rom spline + tap-to-return, dual concentric noise rings, frozen overlay
Integration fixes from fresh-eyes review:
- getCurrentInputs()/setCurrentInputs() use cached pipeline coords (not raw)
- CSS noise ring hidden when canvas version active (no doubling)
- Input mode switch re-runs through pipeline
- Control surface state persisted to localStorage
Implements full Phase 1 of SPEC-controls.md plus bonus items from later phases
(zoom-aware feedback, control presets with override resolution, input curve/deadzone/
smoothing/momentum all wired).

docs(playground): add comprehensive control surface spec
...
Design spec for input zoom, compound control axes, pinning system,
exploration noise controls, and visualization enhancements. Covers
the full parameter inventory with implementation phases and open
design questions for experimentation.
