/**
 * #1267 — VCR bar invisible on mobile /live (iOS Safari ~375x812).
 *
 * RED first: at a 375x812 mobile viewport, the `.vcr-bar` must be visible
 * between the map and bottom-nav. Asserts measured height > 0, display !==
 * 'none', visibility !== 'hidden', and that its top edge is within the
 * viewport (not pushed below the visible area).
 *
 * Usage: BASE_URL=http://localhost:13581 node test-e2e-1267-mobile-vcr.js
