+`echolot-app/scripts/enroll-link.sh [note]` mints a §2.1 bootstrap link on fmr over SSH and prints
+it (plus a QR if `qrencode` is installed, plus the `adb shell am start -a …VIEW -d '<uri>'` command
+when a device is attached). The link carries a single-use token — treat it as a secret until spent.
+Never hand-assemble one: the base64 pin needs percent-encoding, and a pin wrong by one character
+fails as an inscrutable TLS error rather than as a bad pin.
