/* ══════════════════════════════════════════════════════════════════════════
   LAXNAR GROUP — visual system
   ══════════════════════════════════════════════════════════════════════════
   Built to the desk's written brief (§25 / §26):

     ground      near-black #050505
     type        large, clean, modern sans — Inter, with IBM Plex Mono for
                 the technical register
     accent      ONE restrained accent. Electric blue, used sparingly, plus
                 off-white. Explicitly NOT gold, NOT stock-market green/red,
                 NOT gradients everywhere, NOT neon.
     motion      slow and restrained throughout. Bloomberg terminal ×
                 quantitative research laboratory — never a trading channel.

   The previous paper-and-brass identity is gone on purpose: the brief rules
   gold out, and a research organisation reads colder than a merchant house.
