/* AI Automation side — "Arctic Console". Modelled on leftclick.ai's calm,
   centred structure; painted as the cold, technical third side of the brand:
   ice-white paper, graphite ink, hairline blueprint lines, dark console
   panels in Fragment Mono. Neon #39FF14 is status only (running dots, active
   workflow steps, the console caret, CTA hover) and never floods the page.
   Loaded after base.css, which reads the tokens below. */
