/* ==========================================================================
   15 lat Fundacji Politechniki Łódzkiej – strona jubileuszowa (oś czasu)
   Projekt: Figma „15 (Copy)” › www-timeline › „Wireframe - 2” (1440 px).

   • ≥ 1200 px – kompozycja 1:1 z projektem. --u to „1 px projektu”
     (1440 px okna = 1 px; węższe okno skaluje całość proporcjonalnie).
     Elementy .a są pozycjonowane w płótnie sekcji (.cv) zmiennymi
     --x / --y / --w / --h podanymi w pikselach projektu, liczonymi od
     lewej krawędzi panelu treści (x = 116 w Figmie) i od góry sekcji.
   • < 1200 px – ten sam HTML w zwykłym przepływie (układ mobilny 390 px
     i tablet), kolejność czytania = kolejność w kodzie.

   Krój: Pacaembu (docelowy krój marki, licencja komercyjna – nie jest
   dołączony). Jeśli jest zainstalowany w systemie, zostanie użyty;
   w przeciwnym razie strona korzysta z kroju zastępczego Lexend.
   Aby osadzić Pacaembu na serwerze, dodaj pliki woff2 do assets/fonts/
   i dopisz url(...) w regułach @font-face poniżej.
