/* =====================================================================
   Summer Smiles Ortho Event — promo-page component styles.
   Loaded AFTER styles.css. Every colour derives from the shared brand
   variables in styles.css :root (no scattered hex); translucent tints use
   color-mix() so they still track the palette. Buttons, .container,
   .section(+modifiers), .section-head/.eyebrow, and .cta-band are reused
   from the shared stylesheet for cohesion with the rest of the site.
