/**
 * VU Theme Components
 *
 * Reusable visual primitives translated from the a-2 mockup. Scope is
 * WEB-03 only: content-area primitives (layout, buttons, cards, badges,
 * section header, stat block, feature row, spec tile, media treatment,
 * CTA band). Global site chrome (nav, mobile nav, footer) and page
 * assembly (hero, homepage layout, templates) are explicitly deferred to
 * WEB-04/WEB-05/WEB-06 and are NOT implemented here.
 *
 * Icons: a-2 uses emoji as placeholder icons. Per project direction,
 * emoji must not become production icons and no icon library is added
 * here. Icon-bearing components expose an empty slot element intended to
 * hold an inline SVG, supplied later by consuming markup.
 *
 * Composition note: a-2 splits horizontal padding inconsistently between
 * its own wrapper pairs (.sec/.sec-in carries no padding on the inner
 * element; .stats/.stats-in puts padding on the inner element). This
 * file standardizes on .vu-container always owning the horizontal
 * gutter, and .vu-section owning vertical padding only, so the two
 * always compose predictably without double-padding.

 * silently forced every .vu-btn--on-red anchor to inherit the ambient
 * (usually white) text color instead of the intended dark red, invisible
 * against this variant's own white background specifically because it is
 * the only .vu-btn variant whose text color differs from ambient white.
 * Qualifying with .vu-site (two classes) reliably outranks `.vu-site a`
 * without depending on the element being an anchor.
