/*
 * Found on a real iPhone 14 and a real Galaxy S22 on 15 September 2026, after
 * weeks of desktop testing showed nothing.
 *
 * Two faults, both on the screens a customer meets first:
 *
 *   Targets too small   Sign in on the landing page was 32px, and the login
 *                       email, password and submit were 36, 36 and 32. The
 *                       recognised comfortable minimum is 44.
 *
 *   iOS zoom on focus   Safari on iOS zooms the whole page when a form field
 *                       under 16px takes focus. Our inputs were 14px, so a
 *                       customer tapping the email box on an iPhone watched the
 *                       page lurch and then had to pinch back out to reach the
 *                       password. Every iPhone customer, first interaction.
 *
 * Scoped to pointer: coarse rather than a width breakpoint, because the
 * question is whether somebody is using a finger, not how wide their screen is.
 * That covers phones, tablets and touchscreen laptops, and leaves the mouse
 * driven layout exactly as designed.
