/* Lockwood Dental Group — Design DNA
   Mood: Clinical-clean, calm, modern dental clinic — airy and trustworthy,
   not a corporate insurance-broker blue or a warm/earthy trade-shop feel.
   Color: soft clinical white canvas, periwinkle-blue brand + mint accent
   (Committed cool-lane palette — distinct hue from every warm/earthy build
   in this pool, and distinct from the other cool builds in this batch)
   Type: Outfit (display, rounded geometric) + Nunito Sans (body, soft humanist)
   Layout: airy whitespace-heavy hero, rounded card grid for services,
   soft-curve section dividers (no hard grid lines, no split-screen)
   Motion: calm, slow fades — quint easing
   Signature element: a single hand-drawn "smile-curve" line (a continuous
   arc) drawing across the hero, echoed as a recurring soft-curve divider
   between sections
