Low-glare without losing clarity
This page gives the timer a darker, quieter surface even when the rest of the site follows your system theme. It is meant for evening work, dim rooms, stream setups, and second screens.
The controls keep strong contrast and keyboard access, and the timer can load again after caching.
Good for
- Evening focus blocks.
- Second-monitor countdowns.
- Low-light rooms.
- Bedside or studio setups.
