/* CC Lead Engine — Dental Implants Referral Template
   Mobile-first responsive CSS. No frameworks, fast loading.
   Forked from templates/home-services/styles.css.

   Differences from home-services:
   - Calmer palette: deep teal/blue accents, off-white backgrounds.
   - System font stack only (no Google Fonts CDN call).
   - Adds: .btn--call-floating, .compare-table, .cost-table,
     .disclaimer-block, .results-grid, .map-embed, .hero--with-form.
   - .hero--with-form lays out an above-the-fold qualifying form on a
     375x667 mobile viewport (form visible without scrolling).
