   WAPP by Progity - teaser landing
   -----------------------------------------------------------------------------
   Jeden soubor, zadny build. Web ma par sablon a jeden formular; bundler by tu
   pridal krok navic a nic neusetril.

   --- JAK FUNGUJE HERO SCENA -------------------------------------------------
   Cela scena visi na jedinem ubezniku (--w-vp-x / --w-vp-y). Koleje, zar
   i souprava se ridi temito dvema cisly, takze presunout scenu jinam znamena
   zmenit dve promenne, ne prepsat pet pravidel. Prave rozjeti ubezniku a SVG
   geometrie bylo v predchozi verzi duvodem, proc na mobilu vypadal vlak jako
   by prijizdel z boku.

   Souprava je JEDEN uzel (.w-train). Pri priblizovani se zaroven skaluje
   a posouva od ubezniku dolu po ose koleji, takze svetla nejen rostou, ale
   skutecne postupuji k divakovi. Vsechno uvnitr - obe svetla, halo i kuzel -
   sdili stejny pohyb. Diky tomu roste soucasne velikost svetel, jejich
   rozestup i delka kuzelu a kuzel se od svetel nemuze odpojit.
