/* ============================================
   KADR.AI — Chat Bubble + Tooltip (initial CSS)
   ============================================
   Minimalny CSS dla widoczności dymka chatu i tooltipa POWITALNEGO,
   ładowany SYNCHRONICZNIE przed renderowaniem body. Komplementarny do
   chat.css (lazy-loaded po kliknięciu w dymek).

   Powód osobnego pliku (zamiast scalenia z chat.css):
   chat.css jest lazy-loaded przez js/chat-bubble.js DOPIERO po klik'u —
   gdyby reguły dla samego dymka też tam były, dymek nie miałby stylu
   przy pierwszym wejściu na stronę i pojawiłby się dopiero po klik'u
   (nie da się kliknąć dymka który jest niewidoczny).

   Wyekstraktowane z kadr_step3.html (Faza 6.3 audytu) — pozwala na
   HTTP cache (max-age=86400) zamiast re-parsingu inline CSS przy F5.
