   Modal + form — solicitud de reunión comercial

   Built on native <dialog>, so the browser supplies focus trapping, Esc to
   close, the inert background and the ::backdrop pseudo-element. There is no
   design for this screen in the PDF, so it borrows the landing's own language:
   navy headings, the blue primary pill, sky accents and the card radius.
