Research: PNG Export Fidelity & Limits
Hypothesis
Canvas toBlob can reliably export year-scale grids at screen resolution with acceptable memory and time on mid devices.
Questions
- toBlob vs toDataURL performance/memory
- Max safe export dimensions before OOM
- Glyph/text crispness at DPR > 1
Method
- Extend viz harness to export PNG; measure time and size
Acceptance
- Export < 2s for year grid at scale 1.0 on mid device
- Document caps and UX messaging for long exports
Deliverables
- Export pipeline guidance; caps; progress/error UX recommendations
