feat(playground): UI primitive library + /dev/primitives showcase Sixteen primitives at src/primitives/, each with its own .module.css and a .demo.tsx that wires the primitive to live local state. All primitives are typed (strict), pointer-event based (touch + mouse), keyboard-accessible where it makes sense, and free of business logic. Primitives: - Slider, SliderBank: value sliders with optional curve mapping; collapsible sections. - VirtualJoystick, XYPad: 2D pointer input, returning [0,1]^2. - Heatmap: NxN canvas rendering with three color modes (luminance/variance/divergence) and a configurable palette. - OutputDisplay: bar chart of N output values. - TrainingControls: thumbs-up/down/undo + train/randomise + status. - Drawer: portal'd slide-in panel from left or right; ESC + scrim close. - ControlAxis: compound-axis slider (Boldness/Memory/Precision shape) with active-preset hint, endpoint labels, double-tap-to-relink. - ProgressRing: SVG circular progress with optional inline label. - PillToggle: segmented radio control. - ParamEditor: min/max/curve/mute/pin/fixedValue editor for a single param. - JoyMap: zoom minimap with adaptive grid + zoom window, vanishing trail with Catmull-Rom spline + tap-to-return, dual concentric noise rings, region pin overlays, frozen overlay. - WeightHealth: 10-bin histogram + dead/saturating/healthy status glow. - GradientFlow: per-layer bar chart with vanishing/exploding/converged color coding. - LossPlot: log-scale line chart of training loss history. App.tsx now wires the /dev/primitives route to a lazy-loaded PrimitivesShowcase that renders all sixteen demos in a responsive grid. Lazy import keeps the home page bundle ~20 kB while the showcase ships its own ~42 kB chunk. Stream 8 of the rewrite (meml-911).
