 * HassleFree.tech — landing

 * The page is a quiet technical document with one live thing in it: a terminal running the
 * real CLI. Everything else stays disciplined so that panel carries the personality.
 *
 * Colour comes from the product rather than from fashion: `--live` is the same green the
 * CLI paints a running service, and it is used for nothing else.
