/* Core5 on the web.
   The app's law, kept: monochrome — emphasis comes from light, never from hue. The greys are
   the ladder in Theme.swift, so the site and the product are lit the same. What the web adds is
   scale: Apple-sized type, Apple-sized air, and the product itself as the only ornament. */
