🎨 Stylistic: this is a stylistic rule used by the formatting feature.

Enforce spacing around commas in NBT lists. No matter what the settings are, spaces after trailing commas are always removed.

• (object) Root.
  • before: (number) the number of spaces before the comma.
  • after: (number) the number of spaces after the comma.

    "nbtListCommaSpacing": { "before": 0, "after": 1 }
