Zero-heap, asynchronous multi-protocol network server for ESP32 with a fully deterministic memory footprint.
Serves HTTP/1.1 and HTTP/2 (routes matched in insertion order; the parser validates every request byte-by-byte and auto-sends 400/413/414/501 with no application code), with HTTP/3 over QUIC in progress, plus WebSocket (RFC 6455), Server-Sent Events, Basic/Digest auth, static file serving, multipart, JSON, templating, and a middleware pipeline, plus opt-in HTTPS/TLS, SSH, Telnet, and SNMP (v1/v2c/v3). All buffers are statically sized at compile time and no heap is used after begin(); feature flags strip unused subsystems.
