   Two modes share one stylesheet:
     body.site         -> marketing / public pages (hero, cards, pricing)
     body.app          -> authenticated owner app (topbar, dashboard, forms)
     body.public       -> narrow public pay/booking pages
   Design system inspired by modern SaaS (Stripe / Linear).
