-# make-release-key.sh - run ONCE, by the owner. Makes DroidDeck's signing key and gives it to GitHub.
-#
-#   - The key is made on this device, in ~/droiddeck-release-key (outside the repo), with a long
-#     random password written beside it. Nothing secret is printed.
-#   - The key and password are secrets in the signing-main and release environments.
-#     PR build jobs use only the public test key.
-#   - The key's certificate digest - public, not a secret - goes to keystore/release-signer.sha256,
-#     which CI checks every signed apk against. That file is the only thing to commit.
-#
-# BACK UP ~/droiddeck-release-key (both files) somewhere safe - a password manager, a USB stick.
-# Without it no update can ever be signed for the people who installed a signed build.
