   near-square corners, and a lot of whitespace.

   Work Order 1 Task A: the dark-mode block was removed deliberately. The
   approved design (design-direction.html) is light, and the site must stay
   light on a machine set to dark. Do not reintroduce a prefers-color-scheme
   block or a theme toggle.
