; Fold ranges for Nix.
;
; Nix has no syntactic block construct (no `{ ... }` statement blocks)
; - every region is an expression. The folds below cover the
; expression forms that are commonly multi-line in real Nix code.
;
; Capture set matches nvim-treesitter's vendored `runtime/queries/nix/
; folds.scm`, plus the additions noted at the bottom.
;
; Editors compute fold regions from each captured node's range.
; Single-line captures are harmless.
