# 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
