zebra kernel

carrier

Starts a stereo audio stream — registers this tab as a named sink input in PulseAudio (pavucontrol, pactl) with channels=2. The C clients modulate L and R volume independently to transmit data.

keys

ECDH P-256 key pair. Generated once, stored in localStorage. Share your public key with the other side. Paste theirs below. Both sides derive the same AES-256-GCM key — no key ever leaves the browser.

./tx -s TX_SINK -r RX_SINK        # terminal 2: wait for offer + READY

L and R channels carry independent UART streams simultaneously. PA sees channels=2 from this stereo carrier — required for Battle Toads.
