A white hero card holds the headline, Google and email sign-up buttons and a booking widget that cycles through sample events (the full page shows "Office Hours", the thumbnail "Medical Appointment") beside review-site ratings. Below: a logo strip, three numbered how-it-works cards, a benefits grid, a feature-icon grid, testimonials, an integrations band, a tweet wall, an FAQ accordion and a closing CTA card. Sections sit as white cards on a #f4f4f4 canvas framed by thin guide lines.
