// bcnr-selftest.js — end-to-end proof that `window.bcnr` from
// bcnr-preload.js reaches the main-process handlers over IPC and returns

// THESEUS_NO_AUTOSTART=1, imports main.js, then wires the minimum bits
// (session preload + resolver warm-up) itself so the harness stays fast
// and hermetic.
//
// Usage:  npx electron dev/bcnr-selftest.js <name>
//                                             ^ optional; defaults to silentmode.bch
