+# Compila no GitHub, publica no Gitea.

+# O GitHub entra só como máquina de build — é dele que vêm os runners Windows
+# de que o módulo nativo de áudio precisa. A distribuição fica no Gitea, que
+# serve os arquivos a qualquer um: assim o electron-updater não precisa de
+# credencial embutida no app, o que aconteceria com um repositório privado no
+# GitHub.
