 Centralised trajectory generation and streaming module.
 - **Why**: Moving side-to-side linearly in joint space causes the arms to arc dangerously out-of-bounds at the top.
 - **How it works**: Intercepts `Motion.goto(x, y)`, slices the Cartesian straight line into small segments (max `25 mm` by default, configurable in `Motion.CONFIG.SEGMENT_SIZE_MM`), and streams them to the ESP32.
-- **Dynamic Blending**: It monitors `P:` positional updates from the ESP32 and fires the next waypoint *before* `AccelStepper` decelerates (when within `BLEND_THRESHOLD_STEPS`). This produces a seamless Cartesian trajectory with no MCU code changes and allows for future "visual flavor" movement effects (e.g. snaky, erratic).
+- **Dynamic Blending**: It monitors `P:` positional updates from the ESP32 and fires the next waypoint *before* `AccelStepper` decelerates (when within `BLEND_THRESHOLD_STEPS`). This produces a seamless Cartesian trajectory with no MCU code changes.
+- **Motion Effects (`web/js/motion-effects.js`)**: Visual flavor modes (snaky, erratic, jumpy, hesitant, overshoot, random, direct) are encapsulated in their own module to keep the core orchestrator clean. The `MotionEffects` singleton intercepts trajectory generation (`applyPerturbation`) and queue execution (`onWaypointSend`, `getQueueAction`) to dynamically inject BLE speed commands (`SPD:`) or alter queue blending logic (e.g. lowering the blend threshold to force physical synchronization of mid-move speed changes without stuttering).
 - **Simulation Sync**: In simulation mode, `Motion.goto()` instantly updates its internal steps and manually dispatches a fake `ble:status` event containing `P:s1,s2`. This allows all UI components to effortlessly sync their visual state using their existing BLE listeners.
