wowlet: first-run 'be your own node' welcome + deferred startup + non-blocking node toggle. On first launch a welcome dialog lets the user choose own-node vs remote BEFORE any node starts (gated on firstRun; later launches use the saved choice); node start moved past it in WindowManager. Settings toggle now stops wownerod non-blocking (no UI freeze while it flushes LMDB). Copy: 'many recommended', no em-dash
