Universal hologram-organism player — any hologram-cartridge/1.0 JSON renders any creature
in-browser, no per-creature code. Pin a cartridge URL, scan a QR, or paste JSON.
A rapp-static-api/1.0 surface.
Cartridges are content-addressed under versions/<name>/<sha8>.json — each is an
immutable, pinnable fallback. Play any cartridge: player.html?cart=<url>.
