/**
 * Zeyn default UI kit.
 *
 * A quiet, dense visual system for screens people work in all day: grids, long forms,
 * windows and toolbars. Every visual decision reads from the tokens on :root, so an
 * organization themes the kit by overriding a handful of custom properties in its own
 * stylesheet (see docs/theming.md). No web fonts, no external URLs.
 *
 * Theme selection: the system setting by default, forced with
 * <html data-theme="light"> or <html data-theme="dark">.
 * Density: --z-density (1 regular, 0.75 compact) or <html data-density="compact">.
