/* Drebbel, the night shift's app.
   Calm and plain, after Apple's own apps: large titles, grouped lists, one
   clear action per card. Near black at night, light by day (the home's own
   schedule decides). One tint, the brand's sonar teal. Amber only for an
   alert that is ringing, never anything else. No red anywhere.
   Text follows the phone's text size: 1rem is the body size iOS picks. */
