A cozy logic puzzle after dark

Make every
window count.

Read the residents' requests, watch the whole building, and shape one perfectly balanced night with lights, curtains, windows, and visibility.

One building. Many wishes.

A small action can change the whole night.

Every resident follows a personal rule, while building-wide limits connect the puzzle together. What helps one window may complicate another.
