/*
 * ARCHETYPE: Clean-minimal
 * LAYOUT DNA: Text-only hero with massive typography, Symmetric centered layout, Full-width image bands between sections, Tabbed or accordion content
 * SIGNATURE DETAIL: A scroll-triggered gold accent line that traces down the page as you scroll, connecting sections like a timeline of 40 years
 * WHY: A 40-year dental practice with a perfect 5-star rating needs dignified confidence, not visual noise. The legacy speaks for itself.
