// Real-backend smoke harness for the lite wallet bridge. Links the actual SDXL

// LiteClientBridge against a real lightwalletd server. This is the "real backend smoke
// test" the implementation plan gates behind passing fake-backend tests.

//   lite_smoke [server-url] [--create]

// Read-only by default (available / checkServerOnline / walletExists). Pass --create to
// also attempt a real litelib_initialize_new (writes wallet state — run with an isolated
// HOME, e.g. HOME=/tmp/lite_smoke env, so it cannot clobber a real wallet).
