/* Resonans — the product page (web/templates/pages/resonans.html,
   docs/RESONANS.md). Page chrome uses only the --labs-* tokens
   (docs/DESIGN.md, »mörkt labb«): the room is dark and the one thing that
   glows in the chrome is --labs-signal. The button-ring colours are PRODUCT
   DATA — they arrive as SVG attributes from the template and as custom
   properties set by the island from the props — never as literals here.

   Without JavaScript (or WebGL) the theater reads as an ordinary document:
   the sticky 3D stage only appears once the island has added .rs--3d. */
