/* ==========================================================================
   TechToAr V1 — style.css
   Stage 0: variables, reset, typography foundation, spacing system,
   responsive foundation.
   Stage 1: Header/Navigation and Hero styling (sections 9–10).
   Stage 2: Services and How We Help styling (sections 11–12).
   Stage 3: TechToAr Lab styling (section 13).
   Contact form: layout-only alignment fix ahead of Stage 5 (section 14).
   Stage 4: Why TechToAr and About/Founder styling (sections 15–16).
   Stage 5: CTA band styling (section 17) and Contact form validation/
   status states (added to section 14).
   Stage 6: visual polish batches 1–5 (card/icon/chip contrast, button
   hierarchy, hover/focus states, responsive refinements — folded into
   their respective sections above) and scroll-reveal (section 18).
   Remaining: Footer still has no section-specific styling — added in
   a later stage if needed.
