Challenges & trade-offs
- Drawing that feels the same on any screen: pointer positions are scaled onto a fixed-size canvas, and pointer capture keeps strokes continuous with touch and pen as well as a mouse.
- A simple undo: the canvas is snapshotted before each stroke and the history is capped at 40 steps, trading some memory for an undo that is easy to reason about.
- Built on the plain browser canvas API with no drawing library, keeping the app small.
