// TEST: the JS expression lowering must carry two Zig-spelled Koru forms it
// used to pass through raw:
//
// - `var name: f64 = …` — a TYPED declaration inside a kernel op body
// (koru_body mode). Emitted verbatim it reached `node` as
// `var nx: f64 = 0.0;` — a syntax error, not a wrong answer.
// - `if (c) a else b` — the inline conditional EXPRESSION, in koru_body
// (kernel op) AND koru_expr (insert field) modes. The koru_expr path
// reserved-word-mangled `if`/`else` to `if$`/`else$`.
//
// kind>0.5 rows gain 100, others gain 1; the third row's x is itself an
// inline-if insert field. Both targets print the same three rows.
