Visual Regression Playground

Visual regression testing snapshots the UI and compares each new render against an approved baseline. The hard part isn’t spotting differences — it’s telling a real regression apart from harmless sub-pixel noise.

Pick a scenario and watch the diff overlay light up. Switch between pixel-exact and perceptual comparison, then tune the tolerance and threshold to see how the same change flips between PASS and FAIL. More patterns live in the recipes.
