1f21494dee 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.

73eeaac0cc 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).
