/* Appliance Smart Pro - hand-written CSS, no framework, no build step.
   Deploy target is Hostinger shared PHP hosting, so everything ships as-is.

   Design tokens are defined once on :root (light) and swapped wholesale under
   prefers-color-scheme: dark. One accent colour for the entire page.
   Radius rule: surfaces 12px, controls 8px. Nothing else.
   Motion budget is deliberately low: hover/active/focus transitions only, no
   scroll animation. Someone whose fridge just died wants the phone number. */
