/* ==========================================================================
   [CLINIC NAME] — mockup design system
   Palette derived from the client logo (images/logo.png): deep navy +
   cyan/teal caduceus mark on white. Strategy: Committed. Primary (navy)
   carries meaningful surface area across CTAs, accents and media
   placeholders; bg stays pure white, matching the logo's own white
   background, so long-form medical copy and forms stay legible. Accent
   (teal, lifted from the logo's caduceus/wave) supplies the lighter,
   clinical-trust counterpoint.
