	1	+//! The native halves of the JS bridge contracts, in one place.

	3	+//! `test/injected_js_test.zig` drives the real injected JavaScript and then
	4	+//! decodes what it posted with the very code the bridge dispatches to — which
	5	+//! is the only kind of test that can catch a JS side and a native side that
	6	+//! are each individually correct and disagree with each other. Both #27 (menu
	7	+//! action names) and #47 (shortcut payload shape) were exactly that.
	8	+//!
	9	+//! They arrive through one aggregate rather than as two named modules because
	10	+//! both reach `bridge_error.zig`, and a file may belong to only one module per
	11	+//! compilation. A test module also cannot `@import` outside its own directory,
	12	+//! so this has to live here beside the code it re-exports rather than in
	13	+//! `test/`.
