ppu-ocv

Use this skill whenever the user is writing TypeScript/JavaScript code that imports `ppu-ocv`, `ppu-ocv/web`, `ppu-ocv/canvas`, `ppu-ocv/canvas-web`, or `ppu-ocv/canvas-mobile`, or asks about chainable image processing, OpenCV.js, document/receipt preprocessing, perspective warp, deskew, contour detection, or running OpenCV in browsers / browser extensions / React Native / Bun / Node. Trigger even when the user says "image processing in TypeScript" or "OpenCV.js wrapper" without naming ppu-ocv, as long as the codebase imports it. This skill encodes the five entry points, which classes each unlocks, when to pick `ImageProcessor` (OpenCV) vs `CanvasProcessor` (canvas-native), the chainable pipeline order, and the runtime-init dance.
