/**
 * Base styles. Deliberately minimal.
 *
 * This is a SHELL for a later design pass, not a finished skin. It establishes
 * layout, reading order, hit targets, focus visibility and contrast, and it
 * reserves ad space so the design pass inherits a zero-CLS page. It does not
 * establish a brand.
 *
 * Mobile-first with no lower breakpoint: the median visitor is on a phone,
 * standing in a pharmacy, mildly stressed. The desktop layout is the exception
 * handled by a media query, not the default.
 *
 * The design pass may replace every rule in this file. It may not change the
 * engine or its data contract. See docs/v0-handoff.md.
