{#- Zig JSON-struct assertion template.
    Field values come from std.json.Value; type tags accessed with .string/.integer/.bool/.array/.object.

    Context variables:
    - assertion_type: string
    - field_expr:      Zig expression resolving to std.json.Value (already traversed via .object.get)
    - is_length_access: bool — field_expr resolves to an array; use .array.items.len for comparisons
    - zig_val:         escaped Zig string literal (e.g. "\"hello\""), empty string when unused
    - is_string_val:   bool
    - is_bool_val:     bool
    - bool_val:        "true" or "false"
    - is_null_val:     bool
    - n:               numeric literal string
    - has_n:           bool
    - values_list:     list of Zig string literals (for contains_all / contains_any)
