/*
 * I.G.C. concept site.
 *
 * Palette. The live site declares --color-primary as amber 255,179,0 and
 * --color-secondary as burnt orange 216,76,13, then paints most of its buttons
 * in the orange and one italic heading accent in a crimson 207,10,44 that is
 * declared nowhere. Three accents on one page is what makes it read as a
 * template, so this design keeps the orange as the single accent, gives the
 * amber the one job of marking a search hit, and drops the crimson. The ink is
 * the live site's own near-black 17,15,15, which is also the colour of the
 * company's mark.
