Twilight path lighting keyed to sun elevation, not a clock
Garden path lights come on when the sun hits -4° elevation and dim to 30 % at -12°, so the transition takes 25–40 minutes depending on the season and never looks like a switch was thrown.

Lux-adaptive blinds that hold 300 lx on the desk, not a fixed percentage
A closed-loop controller reads a desk lux sensor every 90 seconds and moves the blind to the position that keeps the desk between 250 and 400 lx. On an overcast day it opens fully; on a bright February noon it sits at 22 % open.
