/* ==========================================================================
   Lanrigson I-Tech Limited — design system
   One stylesheet, no build step, no framework.

   Dark-first. The ground is space black — a cold blue-black with a faint
   starfield and one azure horizon glow — and the single accent is azure, the
   colour of a screen actually emitting light. A diagnostic bench at night:
   instruments glow, paper does not.

   Register: mission-control readout. Grotesque display type, engineered body
   and mono, square geometry throughout, and a title-block rule that runs
   beside a label rather than a decorative dash beneath a heading.
