/* ============================================================
   JRX redesign — Nord theme, sim.ai-inspired structure
   No external fonts, analytics, maps, or fonts. Self-contained.
   Palette: https://www.nordtheme.com/
   Aesthetic cues: monochrome-first surfaces, hairline borders,
   corner-tag labels, confident flat type, one restrained accent.
