/* =====================================================================
   Likha Nexus — design system

   Hand-written, no framework, no build step. The development machine has
   git and nothing else, so every byte here ships exactly as written.

   Density is the governing choice: this is a tool someone stands at for a
   whole shift, reading a table of forty rows at arm's length from a
   warehouse terminal. Generous whitespace would mean less on screen and
   more scrolling, so spacing is tight and type is sized for scanning.
