+
+## Goal
+
+Install Playwright and wire a screenshot test harness against Storybook so
+the moment the first component+story lands, the visual regression gate
+is already active.
+
+## Why
+
+Per the frontend-work-shape guide, visual regression is the CI gate that
+locks in component appearance. Setting up the infrastructure now means
+zero ramp-up when components arrive.
+
+## Stories

+- [ ] [02 — Storybook visual test harness](02-storybook-visual-tests/_story.md)
