/**
 * Design-token layer (light mode / default values) + base typography.
 *
 * Brand tokens (primary/secondary/accent/success/warning/danger/info,
 * spacing, font sizes, radius, shadow, transition, container) all come
 * from theme.json and are already available as
 * var(--wp--preset--color--*), var(--wp--preset--spacing--*),
 * var(--wp--preset--font-size--*) and var(--wp--custom--*) — see
 * theme.json for the source of truth. Do not redefine those here.
 *
 * What theme.json CANNOT express is a *second*, dark-mode value for a
 * token. So the handful of tokens that need to flip between light and
 * dark (surface, background, foreground, border) are defined as our own
 * semantic custom properties here, in one place, and every component
 * reads only these semantic names — never a raw hex, never a
 * light-mode-only preset — so dark mode (base/_dark-mode.css) can
 * override them globally with zero component-level changes.
 *
 * Reference breakpoints (kept in sync with theme.json settings.custom.breakpoint;
 * media queries cannot consume CSS custom properties, so these are the
 * literal values every component/layout file should use):
 *   sm: 480px   md: 768px   lg: 1024px   xl: 1280px   xxl: 1536px
