I took a look at the last remaining FIXME comment in the code - the one in `js/app.js` pointing to PR #673. It's from 2017 and was already flagged as a hotfix back then. The problem: `MM_PORT` got written into a global `global.mmPort` that was then read inconsistently across the code - sometimes via the global, sometimes straight from `process.env`, plus separate logic in `defaults.js`. Three ways to get the same port. I pulled this into a single `getServerPort()` helper (`MM_PORT` -> `config.port` -> `8080`) and switched `app.js`, `defaults.js`, `server.js`, `electron.js` and both serveronly files over to it. The global is gone now. Basically the behavior should be unchanged.
