Iteration 5: ? nil-propagation: Field and Index handlers in js_cg_expr now detect when the object expression is a Try node (the AST node for postfix `?`). When detected, emit JS optional chaining: `(expr)?.["field"] ?? null`. The `?? null` normalizes JS undefined to El's null. A bare `expr?` not followed by field/index still passes through unchanged. browser-auth.el: a realistic 130-line example demonstrating: - @async function with Supabase via native_js_call - DOM bridge: get/set value/text/attr, add/remove class, show/hide - local_storage_get/set for session hints - window_on_load for initialization - window_set to expose functions to the browser global scope - set_timeout for transient state, is_valid_email for input validation Compiles cleanly with elc --target=js --bundle Spec updated: status promoted to Phase 4 / ~80% coverage, nil-prop status updated, new example referenced.
