Low-melanopic evening: Bedtime mode (2200K, m-EDI <10 lx) holds through the hour before close, aligned with CIE S 026 guidance for melanopic-suppression avoidance

Invisible fixture: Linear lights recessed into ceiling coves or above furniture - see the light, not the source

Automation: Scene transitions triggered by time-of-day scheduling or smart-home integration (Matter / Thread compatible)

This program includes a pre-configured DALI-2 / Casambi scene file ready for immediate deployment to your lighting controller.
