001 io println cross target

Failed: js-runtime

Failure Output

🎯 Compiler coordination: Passes: 14 (flow-based: frontend, analysis, emission)

Code

// Cross-target stdlib parity: the idiomatic hello-world through std.io must
// produce identical output whether emitted to Zig or JS. `println` resolves
// across the module boundary (std.io is imported, module-qualified), and the
// JS target uses println's |js variant (console.log) while Zig uses |zig
// (std.debug.print). Same source, same output, two backends.
