/* ============================================================
   SERVICE PAGE MASTER TEMPLATE — VisionForge Technologies
   Used by every individual service page (Custom Web Development,
   Mobile App Development, UI/UX Design, API Integration,
   Cloud & DevOps, Maintenance & Support).

   This file is self-contained on purpose (like legal.css) so a
   new service page only needs ONE stylesheet link plus its own
   content — never new CSS.

   Section prefixes:
   sp-hero      1. Service Hero
   sp-overview  2. Service Overview
   sp-benefits  3. Key Benefits
   (Key Features reuses the GLOBAL .service-card / .services__grid
    components already defined in style.css — no CSS here.)
   sp-process   5. Development Process (adapted from services.css .dp-*)
   sp-stack     6. Technology Stack
   sp-cases     7. Related Case Studies (adapted from case-study.css .cs-related-*)
