/* =============================================================
   MaxPanel design system — theme.css
   Foundation stylesheet for the public site + customer portal.
   Loaded FIRST (before public.css / portal.css). Dependency-free:
   system font stack, no external CDN, no @font-face.

   Brand hue is #FE64B0 (--brand-400) used for accents / glows /
   gradients ONLY. Interactive surfaces that carry white text use
   --brand-600 (#C81E78), which passes WCAG AA (4.6:1 on white).

   Contains: design tokens, base reset, and the shared component
   layer (buttons, cards, forms, badges, tables, nav, footer, flash,
   icons) + motion utilities. Respects prefers-reduced-motion.
