/*
 * Israsky homepage, concept 2D "Hybrid": the light page of concept A (the
 * Ribbon) with the violet first screen of concept G (Ink). The Ribbon
 * leaves the violet field through a 45-degree fold and runs on into the
 * light page. Base: concept 2 "Digital department: the whole process". One
 * device carries the page: the Ribbon, an orange strip folded at 45 degrees
 * (geometry of the Israsky mark). Everything else stays quiet: two
 * typefaces, one radius, no shadows, no gradients.
