   Dark, terminal/hacker-themed styling for the public marketing
   site and the shared auth page shell. Vanilla CSS3 only (no
   Sass/Less build step), so it can be dropped straight onto
   shared hosting. Bootstrap 5 is intentionally NOT used here --
   this hand-rolled sheet keeps the exact BitCops aesthetic and a
   minimal footprint.
