// Thin fetch wrappers around /api/v2/*. Kept minimal — no state
// library; each page owns its own useEffect + useState.
// API base:
// * dev (vite proxy) → '/api'
// * prod local → '/api' (SPA at :7700/v2/, API at :7700/api/)
// * prod via Tailscale → '/clawstor/api' (SPA at /clawstor, API at /clawstor/api)
//
// Detect at load time by checking the current URL's pathname
// prefix. Cheap + no build-time coupling.
