aa0ffcfd32 feat(playground/nisps): recency & spatial weighted training in JS ML engine
Add Dataset.computeWeights() with three modes:
- global: exponential recency decay (newest examples weighted higher)
- local: spatial suppression of older examples near the current input
- combined: both applied together

IML and WasmIML now compute weights on every train() call using the
active mode. Exposes recencyBias, weightingMode, localRadius properties.
WASM worker path passes sampleWeights through to C++ via the new binding.

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.

3db90b035a feat(playground): add spread param for sigmoid saturation control and fix randomise sync
Add ?spread=0-1 URL param that controls weight initialization scaling,
RL noise scaling per layer, noise cap, and weight decay to prevent
sigmoid output saturation. At spread=0 (original behavior) weights are
uniform [-1,1] and outputs polarise near 0/1. At spread=1 weights use
Xavier scaling (1/sqrt(fan_in)), noise is proportionally reduced, and
10% weight decay per thumbs-down prevents unbounded magnitude drift.

Also fix randomise to re-inject current joystick position and re-run
inference before routing outputs, eliminating the jump on first
joystick move after randomise.

Defaults: tame=1, spread=0.6 across all app variants.

d9be808aaa style(playground): unify dark theme with orange accents and improve RL button layout
- Replace fragmented green/blue/orange accent scheme with unified hacker
  orange (#ff6a00) across all CSS, JS canvas drawing, and param palettes
- Redesign designs.html: monospace font, clickable cards, grid background,
  remove A/B/C labels; copy to index.html as landing page
- Add JetBrains Mono font across all views for consistent techy aesthetic
- Sharpen border-radius (pills 20px→6px, back buttons→6px) for angular feel
- Restructure RL buttons: key numbers inside buttons (larger, white),
  teal-green for thumbs-up, dark red-orange for thumbs-down
- Fix RL button z-index (25→45) so they render above the bottom sheet
- Add Xavier-scaled weight randomization (spread parameter)

57aae34870 feat: add web-based interactive playground for NISPS
Faithful JS port of nisps-core MLP + IML engine with a touch-friendly
UI for exploring neural parameter mapping visually. Two learning modes:
example-based (set slider targets) and RL feedback (thumbs up/down with
exploration noise). Flow field particle system controlled by 8 MLP outputs.
