• Fix text disappearing after hovering a frame (revert SkPicture scene caching)
• Fix macOS startup hang: async font loading, show window on reopen

0.3.0 (2026-03-01)

Performance

• SkPicture scene caching — pan/zoom replays cached display list instead of re-rendering all nodes
• Cache vector network paths — avoid rebuilding WASM paths every frame
• Cache ruler and pen overlay paints — eliminate 10 WASM Paint allocations per frame
• Only enable preserveDrawingBuffer in test mode
• Hoist URL param parsing out of render loop

Fixes

• Fix npm publish: use pnpm for workspace dependency resolution with provenance
• CLI version now reads from package.json instead of hardcoded value
• Update README: accurate app size (~7 MB), streamlined feature list, current project structure
