Batch 19: Layout defects found by device emulation

Every page rendered on ten emulated phones and tablets — real Playwright device profiles, so 768 means 768 and there is no scrollbar inset — and measured against each box's nearest clipping ancestor rather than document.scrollWidth, which this site's body{overflow-x:hidden} makes agree with the viewport while content is sliced off the right edge.

First sweep, at build a25077d plus the Batch 17 and 18 work: 190 page loads, 21 blocking and 530 high findings, on pages that had passed Batch 11 and Batch 16.

Landed when a sweep of all ten devices reports zero blocking and zero high, and re-introducing each defect makes it report them again.
