Resolution Test
Inspect current resolution, DPR, 1px lines, pixel grids, and sharpness samples to see how crisp the panel looks in the browser.
If 1px lines look blurry or broken, the cause is often scaling or the current rendering path.
The values shown here are browser-visible dimensions and pixel ratios, not a full low-level display report.
