Hotel room
The guest has to understand the controls in ten seconds, in the dark, after a flight. Everything else is secondary.
The hotel room is where control most often becomes too clever. Four named modes by the door and a reading light per bedside beat any twelve-button panel, however well thought through.
The night path to the bathroom is the detail guests remember: a low level triggered by presence, enough to find your way but not enough to wake up fully.
Arrival, evening, reading and night. More choices make the room harder, not better.
A low level on presence, so the guest finds the way without waking.
An empty room should not stay lit. Handled centrally, not by housekeeping.
