/* ============================================================
   Racklog — web (úvod, přihlášení, changelog, 404).

   Stejná identita jako aplikace („Rozvaděč"): grafit jako čelo
   rozvaděče, teplý technický papír s rastrem, signální jantarová
   štítků, hlavní akce ve tvaru visačky na kabel, nadpisy jako páska
   ze štítkovače. Písma jsou ta, která aplikace vozí s sebou
   (/app/fonts.css) — žádné cizí servery, nikdo se nedozví, kdo web čte.

   Pohyb: každá animace má smysl z rozvaděče (LED, kabel, visačka)
   a při „omezit pohyb" v systému se celá vypne.
