- Remove the top-of-file "IMPORTANT: Remove WLED naming throughout the
app" checklist. The effort was absorbed by the multi-backend refactor
(BLE / USB-serial / ESP-NOW / MQTT / OpenRGB providers all shipped),
and the remaining user-facing copy has been swept in separate commits.
- Add an "Android Signing Secrets (Gitea)" section covering the four
secrets the release APK CI expects, the one-off `keytool` command to
generate `release.jks`, the consequences of losing the keystore, and
a checklist of the remaining setup steps before tagging v0.4.1.
