/* AuditPrep.
 *
 * Everything here is fluid. There is no fixed-width shell anywhere in this
 * file: the standing law is that every page works on a phone, and the way
 * that gets broken is a `width: 1100px` on a wrapper that looks fine on the
 * laptop it was written on. Max-widths only, and every table that can
 * overflow is wrapped in .scroll-x rather than allowed to widen the document.
 *
 * Proven, not eyeballed: tests/mobile_layout.mjs loads every page at 360,
 * 375 and 390 CSS pixels and fails if scrollWidth exceeds the viewport.
