- Remove Arpeggiator import and all arp references from a-app.js
- Add ShapeSeq imports (ShapeSeqEngine, StepVisualizer, ChainBuilderUI,
getDefaultBus) and lazy initialization on first audio start
- In synth mode: show ShapeSeq container (circular viz + chain builder),
hide flow-field particles. Visual mode unchanged.
- Route joystick or hand tracking inputs to shapeSeq.setSequenceInputs()
each frame; render step viz at 60fps
- Add HTML: #shapeseq-container with #shapeseq-viz canvas and
#shapeseq-chain wrapper, sequencer transport controls (play/stop,
tempo, step count)
- Add CSS: full-screen flex layout, viz takes upper 45%, chain builder
scrollable below, hidden by default
- Quick play button wires to ShapeSeq start/stop instead of arp
Closes meml-6ry. This completes ShapeSeq Phase 1.
