The phone experience as a first-class citizen.

Mobile web annotations on the mobile capture1234
  1. BOOK A DEMO button — Primary CTA sits below the fold on mobile — the eight-line body paragraph and tall headline push it out of the first viewport.
  2. Body paragraph block — Desktop-length copy wraps into eight lines on the phone, burying the CTA and forcing a scroll before any action is reachable.
  3. Eyebrow badge pill — Three stacked category phrases in tracked-out caps wrap to two dense lines, adding a competing message above the headline.
  4. BOOK A DEMO width — Button keeps desktop proportions instead of going near-full-bleed, shrinking the thumb target.
