Tips & notes
Keep these quick hints handy when you wander through formats and workflows.
Always back up your raw .mma assets before running the bundler. Overwriting the default
cache can break an entire release if the wrong hash is pushed.
Haruspis logs link directly to the workspace path. Use the Diagnostics menu to open the log folder with a single click and avoid hunting through hidden directories.
