/*
 * Aqualytix — "Calm Scientific Instrument" design system.
 * See docs/design-system.md. Structure comes from background zones, type and
 * space — not cards. Rules: (1) no cards/outlines/shadows on content, groups
 * are separated by background value + 1px hairline dividers; (2) the teal
 * accent marks only the primary action and active nav — all other color is
 * status severity; (3) one type family (IBM Plex Sans), figures use tabular-nums.
