Vadim Makeev tries CSS Linked Parameters, a new spec running in Firefox Nightly and behind a flag in Safari TP. The SVG file writes env(--color, fallback) wherever a value goes, and the page passes it in with link-parameters: param(--color, coral). A Warhol print in SVG, referenced nine times as <img>, comes out in different color schemes from one cached file. Browsers without support render the fallbacks.
