automate all store texts and graphics

F-Droid now supports Fastlane Supply and Triple-T Gradle Play Publisher for getting app store graphics and texts:

If you include all your store materials in this git repo using either one of those tools, F-Droid will automatically include them. As of 0.103, F-Droid supports graphics, screenshots, and localized texts. Since this app is not on Google Play, I think using the Fastlane file layout makes the most sense. You can use the _fastlane_ command line tool to download all the materials from Google Play, if they are still posted there.
