/* Vertizin — the public page.
 *
 * THE PALETTE COMES FROM THE LOGO, not from the app.
 *
 * The mark is a black wordmark with a golden-amber angled stroke on the V and
 * an amber exclamation point, on a white ground. There is no green in it at
 * all — so the app's cream-and-deep-green family does not carry over, and
 * pretending otherwise would have produced a page that clashes with the one
 * thing on it nobody can change. The amber is sampled straight off the file:
 * #FEC303.
 *
 * Two consequences worth stating, because both are contrast decisions:
 *
 * 1. AMBER IS NEVER TEXT ON WHITE. #FEC303 on white is about 1.7:1 — unreadable
 *    as body copy and marginal even as a heading. It earns its place as a
 *    block, a rule and a button GROUND, where black sits on it at roughly 11:1.
 * 2. The buttons are therefore amber with black type, which is the logo's own
 *    combination rather than an invention.
 *
 * The logo file is a JPEG with a BAKED WHITE BACKGROUND. There is no
 * transparency to work with, so it only ever sits on white sections; the
 * alternating bands are the warm off-white below and the logo never touches
 * one. Fighting a baked background with blend modes would look like a fight.
