Overview
A React Native component for draggable, pannable, pinch-to-zoom, and optional rotation gestures.
Why it mattered
Mobile products often need direct manipulation for images, documents, maps, and diagrams without rebuilding gesture behavior from scratch.
Key decision
Expose a small wrapper component with configurable gesture limits, action buttons, and state callbacks instead of forcing consumers into a rigid viewer UI.
Hard part
Combining pan, pinch, and optional rotation meant keeping gesture state predictable while still allowing flexible content inside the component.
