/* Tian Woo PVD — version 2.
   Concept: "thin film". PVD colour is light interfering inside a coating a few hundred nanometres thick.
   A cool steel ground, condensed industrial type at poster scale, and one bold element used sparingly:
   the thin-film spectrum (violet → blue → teal → gold → copper) that appears on our iridescent parts. */
