Subject: [PATCH] feat(playground): add tiered synth parameter preset system
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

4 tiers of progressive complexity (Beginner 15 params → Expert 126),
13 presets total with per-param min/max/curve overrides that bias
distributions without clamping extremes. Preset dropdown in UI,
persisted to localStorage, supports ?preset= URL param.

+### Synth Presets
+
+Presets (`js/synth/presets.js`) control which parameters the ML engine can modify, with unselected params muted at safe defaults. Each preset defines per-param `{ muted, fixedValue, min, max, curve }` — no training examples or model weights.
+
+4 tiers of progressive complexity:
+
+| Tier | Presets | Active params | What's exposed |
+|------|---------|---------------|----------------|
+| 1 (Beginner) | 1.1–1.4 | 15 | Basic ADSR, SVF cutoff/res, Shaper A drive/fold, output levels, reverb mix |
+| 2 (Intermediate) | 2.1–2.4 | 40 | + Env B/C, filter FM, effects (reverb/echo/flanger), cabinet, stereo panning |
+| 3 (Advanced) | 3.1–3.3 | ~95 | + Cross-oscillator PM, feedback mixer, dual shapers, comb/gap filters, ring mod |
+| 4 (Expert) | 4.1–4.2 | 126 | Full engine |
+
+Presets use `curve` values to bias parameter distributions (< 0.5 = spend more time low, > 0.5 = bias high) without clamping extremes. Users can tweak any preset via the group drawer after loading.
