/* =========================================================
   Nabídky klimatizací: tmavá pracovní deska, světlý list
   Aplikace je noční modrá deska jako obě ukázky. Jediný světlý předmět
   je papír: proužek s cenou dole a z něj náhled nabídky. Ledová barva
   jen pro hlavní akce, „trubku“ sestavy a tečku „upraveno“.
