/*
 * Responsive styling baseline for the customer web app.
 *
 * PLAIN MODERN CSS ON PURPOSE — custom properties, layout primitives and media queries. There is no CSS
 * framework or utility-CSS library here, deliberately: a framework would be one more dependency to keep
 * current, and it would push a look onto apps whose design, copy and page composition are meant to stay
 * app-specific. This file is a NEUTRAL FOUNDATION, not a design system: it makes a fresh scaffold work on
 * a phone, and every app is expected to restyle on top of it (override the tokens below first — most
 * re-skinning needs nothing else).
 *
 * Mobile-first: the base rules target the narrowest viewport and media queries add capability as the
 * viewport grows. The bar a scaffolded app must keep meeting at 375px / 768px / 1280px is: no horizontal
 * scrolling, nothing clipped or overlapping, interactive targets at least 44x44px, and navigation that
 * ADAPTS its layout rather than merely shrinking.
