   VeraCita marketing site — MOBILE OVERLAY
   ----------------------------------------------------------------------------
   Loads LAST, after cream-theme.css. Every rule in this file lives inside
   @media (max-width: 768px), so it is structurally impossible for anything
   here to affect the desktop rendering. Do not add a rule outside the query.

   Scope: veracita.ai marketing site only. The app (app.veracita.ai) is a
   separate surface and is deliberately desktop-only.
   Intent (Andy, 2026-08-02): mobile is a full acquisition surface — browse,
   sign up and buy must all work on a phone.

     (css/sections/founder.css:15) centred with left:50%/translateX(-50%),
     so it reaches x=591 in a 383px viewport and drags the whole document
     sideways. `clip` contains it without creating a scroll container the
     way `hidden` would (which would break position:sticky descendants).
     The html/body rule is a backstop for any future wide decoration.

     6. CHECKOUT / SIGN-UP  — the money path
     Two real defects fixed here:
     (a) inputs were 15px; iOS Safari auto-zooms the viewport on focus for
         anything under 16px, which throws the user out of the form layout.
     (b) .checkout-dialog had max-height:none + overflow:visible, so on a
         short viewport (iPhone SE, or any phone with the keyboard open)
         the submit button can sit off-screen with no way to scroll to it.
