Right now, data is recorded every 0.05s.
Tried 0.1s — interpolation still looks smooth, but needs more testing.
Result: file size reduced almost 3× compared to the first version.

Third (current) version:
- Fully numeric array
- No string keys
- All booleans packed into one byte via bit flags
This gave the biggest compression boost.

#3 (43.7 KB, current format)
[0.0575,70.1,1.2,11.0,1.4E-07,0.7071,1.01E-05,0.7071,2.4,0.0,0]

Second iteration:
- Shortened field names
- Still stored booleans separately
Big improvement, but still not perfect.

#2 (81.7 KB, intermediate format)
{"t":0.055,"pX":70.1,"pY":1.2,"pZ":11.0,"rX":-3.5E-07,"rY":0.7071,"rZ":1.06E-05,"rW":0.7071,"v":2.4,"s":0.0,"flags":0,"d":false,"l":false,"b":false,"c":false}

First version was the worst:
- Saved data every frame
- Very long field names
- All booleans stored separately
Result: unnecessarily bloated files.
