/* Techno Edge — the unapaulogetic system.

   Tokens from the main site's brand-tokens.css, as in Planet Maker. Nothing is
   rounded, and signal green is spent on one thing at a time: the selected
   pattern, the beat light, the primary action.

   The output itself is not branded. An LED wall shows #090909 as a dim grey
   glow, so the screen's background defaults to true black and the interface
   colours stay out of the picture. */
