// Self-hosted HDRI environment map (drei's "city" preset, copied into public/env
// so Vite emits it under the app base). The viewer must never depend on an
// external CDN at runtime: drei's `<Environment preset="...">` fetches the HDRI
// from raw.githack.com, which the site CSP (connect-src 'self') blocks — and
// because <Environment> loads via Suspense, that rejected fetch throws and tears
// down the whole WebGL canvas ("3D not working"). Pointing `files=` at this
// same-origin URL keeps it within CSP. import.meta.env.BASE_URL makes it work
// whether the app is served at "/" or under a subpath like "/demo/".
