// The vis testing battery as a library.
//
// Every manual testing entry point this project has — bank songs, scenes by
// family, venues, param/scenario combos, the throwaway lab pages and the
// headless CLI runners — collected in one place so debug.html (and anything
// headless later) renders them from the live registries instead of a stale
// hardcoded list. Adding a song, scene or venue updates the battery for free.
//
// Pure URL builders + data: no DOM, no WebGL, no wall-clock. Safe to import
// anywhere, including node (nothing here touches metadata.json, which needs
// Vite's JSON handling — so scene *coverage* is deliberately not imported).
