/*
 * ════════════════════════════════════════════════════════════════════════
 * AI-TERMINAL — design system for /ai/* pages. Loaded AFTER /bizops.css.
 * v3 — single white/purple theme (dark mode removed per direction),
 * 3-item nav, fixed mobile-nav-panel default-hidden bug, refined
 * professional type scale inspired by Stripe/Linear-style SaaS UI.
 * body.ai-theme remaps every legacy bizops.css token, so every existing
 * generator (ai_pages_generator.py, build_flagship_pages.py) re-themes
 * automatically without its internal CSS being touched.
