// Current regression after removing nine unused SW Header demo pages (2026-10-19, 19 -> 10 SW Stories).
// Build Storybook first. Usage: node packages/sw/tests/storybook-unused-removal.browser.mjs [evidence-dir]
// Older scripts that open the retired IDs (followup-four, property-close, property-fields, detail-buttons
// composition-history, property-panel-comparison before) are historical evidence for their runs. Since 2026-10-20
// detail-buttons, property-panel-comparison verify and storybook-cleanup-stage1 run on current public Stories again.
