/* ============================================================
   Loistimo Oy – muotoilujärjestelmä
   Suunnitteluperiaate: toimitustyylinen (editorial) ja pelkistetty.
   Vaalea lilapaperi, syvä luumu musteena ja keisarillinen purppura
   korostussävynä. Ei liukuvärejä, ei hehkuja, ei kiiltoefektejä,
   ei emojeita. Rytmi syntyy typografiasta, viivoista ja tyhjästä
   tilasta.
