/*
 * Feuille Claire, product site.

 * Written phone first. The base rules below are the phone layout: single
 * column, nothing narrower than a finger, nothing smaller than 14px. Wider
 * screens only ever ADD density through min-width queries, so a layout can
 * never be discovered by a phone as a desktop screen squeezed shut.
 *
 * Two invariants hold at every width:
 *   1. no fixed pixel width above 400px, anywhere;
 *   2. every interactive element is at least 44px in both axes.
