// Historical since 2026-10-19: opens SW Story IDs retired by the unused demo removal (property-panel). Kept as evidence
// for its recorded run; current regression: storybook-unused-removal.browser.mjs.
// Property panel close button (Figma 26:12366): canvas bleed, Default / Hover, close by click and Escape.
// Usage: node packages/sw/tests/property-close.browser.mjs <evidence-dir> <label> [storybook-url]
// Storybook serves packages/sw/dist: build @hm-design/sw first.
