/* =====================================================================
   DOCTOR PROFILE TEMPLATE
   A dedicated, self-contained stylesheet for individual physician
   profile pages (best-dentist-in-hrbr-layout.php, best-dermatologist-
   in-hrbr-layout.php). Intentionally distinct from the marketing/service
   page system in main.css / services.css — editorial layout, a serif
   display face, and a muted per-doctor colour theme instead of the
   site's default gold.

   Scope: everything lives under .dp-page so the shared nav/footer chrome
   is untouched. Two theme classes carry the per-doctor palette:
     .dp-theme-dental  → Dr. Lalith  (ink navy + antique brass)
     .dp-theme-derma   → Dr. Premalatha (aubergine + terracotta)
