Added a proper dark/light theme toggle so the board matches both the screenshots and everyday use. The preference is stored in localStorage and respects the system setting on first visit, with no flash of the wrong theme. I also cleaned up the visual hierarchy clearer table rows, better contrast on status pills, and calmer spacing around the filters — so the UI feels less busy in both modes. Took about 1 hour and makes the dashboard much more comfortable to use day or night.
