   SERVICE INNER PAGE — service.css
   Standalone stylesheet. Shares design language with main site.
   One file governs all three service inner pages.

   Architecture:
   — CSS custom properties for full theme control
   — Every layout built with CSS Grid / Flexbox
   — Zero magic numbers — spacing via a consistent scale
   — Mobile-first responsive breakpoints
