For AMP pages, email opens, and IoT firmware that can't run JS. The browser/agent loads the pixel; the server records a single heartbeat beacon. Returns a 1×1 transparent GIF.
Status — coming soon.
Auth

Response — 200
Content-Type: image/gif
Content-Length: 43
(43-byte 1×1 transparent GIF)
Side-effect: one heartbeat row appended to the audit entangled state.
Note that public keys on the querystring DO appear in CDN access logs — that's an acceptable risk for read-only-public keys. Treat any key on a pixel URL as already-public.
