 * @file 20.Diagnostics.ino
 * @brief Compile-time configuration endpoint (DETWS_ENABLE_DIAG).
 *
 * server.diag(slot_id) serves DETWS_DIAG_JSON - a compile-time snapshot of the
 * enabled features and buffer sizes. Handy while developing; it exposes the
 * build configuration, so keep it OFF (or behind auth) in production.
 *
 * NOTE: this feature is compiled into the library only when DETWS_ENABLE_DIAG
 * is set for the whole build (a .ino #define does not reach the separately
 * compiled library). In platformio.ini:
 *     build_flags = -DDETWS_ENABLE_DIAG=1
 * (Arduino IDE: it is already set for you in the build_opt.h beside this sketch, so it builds as-is.)
 *
 * Flash, open Serial @ 115200 for the IP, then GET http://<ip>/diag.
