/* The showcase of the signature designs (src/pages/signature.mjs), 2026-10-20.
   On top of site.css and home.css: the hx- type and buttons, paper, ink and tape yellow.
   Each design carries its own colour (--tint, from its finishes) into its tiles and frame.
   The evening render swaps in on "Lights down"; without motion it simply switches. */
