/* AQN Lab — refined institutional design system (ACS-inspired, restrained).
 * Rules: violet is an ACCENT (buttons, links, active states, thin rules); one large violet surface per page at most (home hero).
 * Radius: --r 12px panels, --r-sm 10px images; pills only for buttons and the segmented control. No shadows (dropdown excepted).
 * Metadata is plain text (no chips/badges). All tokens live in :root. Mobile-first. No external fonts or requests.
 * Type: Sen (Blocksy Cleaning Service starter) — body + headings, self-hosted. */
