/* Gawędka w przeglądarce, wersja klasyczna: gęsty, funkcjonalny układ jak w dawnych komunikatorach (lista kontaktów po lewej,
   zapis rozmowy po prawej, zwykłe przyciski z cienką ramką). Niebieski gradient zostaje tylko tam, gdzie był: pasek z moim statusem,
   zaznaczony kontakt i przycisk główny. Bez bąbelków, bez dużych zaokrągleń, bez cieni. */
