/*
 * Built into every translation unit via -imacros, so a node becomes a
 * standalone NAT64 translator just by building the module:
 *
 *  - Route the node's routeless (off-link) traffic through the standalone
 *    fallback interface, so NAT64-prefix destinations reach the translator.
 *  - Drop the platform's default route to PREFIX::1 (platform.c). With no
 *    border router it is unreachable, and as a default route it would shadow
 *    the fallback interface.
 *  - Enable NAT64 without the --nat64 flag (nat64-sock.c). Building the module
 *    already says "this node is a NAT64 translator", and it keeps enablement a
 *    compile-time choice that matches the route suppression above. Otherwise a
 *    build without the flag would have neither a default route nor NAT64, and
 *    could reach nothing off-link.
