Was it intentional that the previous code would wait two frames for numofcycles==1, three frames for 2, etc?

This is a functional change, both aesthetic and code-simplifying. I can easily undo the right aligning and approach the code reduction here another way.

This is purely an aesthetic change, moving the always-blank row from the bottom of the screen to the top of the lines output, so there will be a gap between the map and the lines.

This PR is a work in progress. I have not been able to fully test all of the changes yet, as I haven't re-explored the whole story. I will do so, but wanted to submit this for feedback beforehand.
before (minified): 6475 tokens, 32610 chars, 99.38% compressed
after (minified): 6350 tokens, 30032 chars, 97% compressed
The biggest savings came from altering the "JSON" syntax to not require quotes around most strings. This makes them harder to edit in other json-aware programs, but still pretty much entirely human readable and hand-editable.
Other savings came from inlining functions and typical token golf optimizations. I suspect there's another 50 tokens, 500 chars, and 1% compressed size to be saved through further more complicated efforts of this sort. I'd be happy to attempt more in that direction if you're interested.
I will comment a few places in the PR that stand out as notable and possibly objectionable, some of which are aesthetic in nature.
If these changes are welcome here, I would also be happy to port the relevant ones over to Minima.
