 I'm not sure why this is the case, but it happens for _both_ options: timescale
 (which does not involve lofitime) and the date picker (which uses lofitime).
 I'm pretty sure lofitime isn't the problem here.

+I discovered [`Vinermy/astray`](https://github.com/Vinermy/astray) and found the
+terminal UI charming. `astray` uses
+[`joshka/bevy_ratatui`](https://github.com/joshka/bevy_ratatui), a Bevy wrapper
+for the popular terminal UI crate [ratatui](https://ratatui.rs/).

+Another inspiration: [`victorb/dogoap`](https://github.com/victorb/dogoap)
+([demo](https://victorb.github.io/dogoap/)) It's a GOAP library. Nothing too
+special about it but it looks the way I want this to look with entities spawning
+and moving around.

+Fresh eyes help. Some refactors today to make the code feel more "natural".
