/* ==========================================================================
   CONTACT FORM — ramy.photos
   --------------------------------------------------------------------------
   Styling only. The markup, the field names, the honeypot, the token and the
   backend contract in templates/contact.php are untouched, which is why this
   is CSS and not a template fork.

   Two names matter and are easy to confuse:
     input[name="mail"]   the real address field, visible
     input[name="email"]  the HONEYPOT, wrapped in <p style="display:none!
                          important">. ContactRequest.php:140 rejects the
                          submission unless it is present AND empty, so nothing
                          here may give that <p> a display value. No rule below
                          targets it; the grid rules address the two fields by
                          name so the honeypot is never selected.

   Every selector is prefixed `body main form.form-background` so it outranks
   _base.css and mode-dark.css regardless of where this sheet is loaded.
