   RENKO — CHIRAL design system · soft-cyber layer (docs/ui/RENKO_UI_SYSTEM.md)
   ─────────────────────────────────────────────────────────────────────────────────────────
   Soft, holographic HUD in the spirit of Death Stranding: hairlines instead of slabs, cool
   pale light, one accent (theme colour) + one gold highlight, corner brackets, chamfered
   controls, Orbitron for every piece of interface chrome, calm motion that "materialises".

   Loaded last (after Tailwind, renko.css, renko-forms.css). Colours are ONLY theme tokens
   written by static/js/renko-theme.js — every mode (dark · deep-dark · light) and every accent
   applies everywhere. Display switches on <html>:
     data-anim="on|off"   animations (user setting + prefers-reduced-motion)
     data-fx="on|off"     ambient background (strands + dust canvas)
     data-font="mix|orbitron"   Orbitron for chrome + Exo 2 for reading, or Orbitron everywhere
