/* ═══════════════════════════════════════════════════════════════
   Formularz kontaktowy MDM Labs — style wspólne (prefiks .kf-).

   Używany przez: kontakt.html, uslugi.html.
   Jeden formularz, jedno źródło stylów — zmiana tutaj zmienia
   wygląd na WSZYSTKICH stronach, które go osadzają.

   Zakłada zmienne z :root strony (--red, --white, --radius-card …)
   oraz fonty Montserrat + DM Sans.
