/* KT Rain Watch
 * Scene: one person, phone in hand, at home at night during a storm, lights
 * low, checking in five seconds whether the canal is about to overflow.
 * -> dark by default (light when the system is light), facts glow, nothing
 * decorative. Accent is rain-cyan so it never competes with the semantic
 * warning colours (red / amber / green carry state, and only state).
