/* HomeBox — app styles on top of Framework7 (iOS theme).

 * Colour system (wiki/frontend.md#colori): palette taken from the app icon
 *   yellow #FFD15D · amber #F9B54C · night blue #2B3B4E/#324A5E · coral #FF6472/#C75163
 * Light and dark values follow the OS setting (prefers-color-scheme). Framework7 runs with
 * darkMode: 'auto', which toggles html.dark from the same media query, so the two always agree.
 * Every text/background pair below meets WCAG AA (≥ 4.5:1 text, ≥ 3:1 graphics).
