The signer reads stdin to EOF, so pressing Enter submits nothing and a
second paste simply appends to the first. Step [6b/8] said only "paste the
release master mnemonic when prompted", which gives no hint that Ctrl-D is
what ends the input — a 24-word phrase arrived today as "invalid word
count: 89", about four pastes concatenated by someone reasonably assuming
Enter had not worked.
sign-manifest.sh already explains this properly; create-release.sh now says
the same thing, including that pasting twice is itself a failure mode.

`npm run build 2>&1 | tail -3` threw away npm's exit status, so a failed
build was indistinguishable from a good one. The run continued and blamed
the next check instead — "the frontend build no-opped or its output is
stale" — which points at a stale dist rather than at the build error that
actually happened, and cost a diagnosis cycle today.
Success still prints the same quiet 3 lines; a failure now prints the real
error, keeps the full log, and aborts on the spot.
Verified both branches with a stubbed npm.
