 * css/lab.css: the lab page (/lab). Layout and components of SPEC-DESIGN.md 5.4 (list rows), 5.6 (lab layout),
 * 5.7 (results panel), 5.9 (empty states), 5.13 (buttons, inputs, segmented control, chips, progress bar), plus the
 * v2 parts of SPEC.md 9.1 (payment cards), 9.4 (row links) and 9.7 (the method panel, a sheet on a phone).
