/* Nagomi — nagomi.day
 *
 * One committed look: deep water, high contrast. Deliberately NOT a light/dark pair.
 * docs/DESIGN.md §2(b) argues the brand should read as an instrument rather than a spa,
 * and §2(a) warns that the pale blue-teal wash is the wellness category's house style.
 * A single dark treatment matching the app icon says both things at once.
 *
 * Colours come from docs/DESIGN.md §3. The accent is the design system's DARK-mode accent
 * (#7FC7D9), because this page is always dark.
