// TestFormatPrintWidthBreaksLongNamedExports verifies `export { … };`
// local exports reflow when the clause overflows the budget.
//
// NamedExports shares listShape with NamedImports, but the surrounding
// declaration is different (no `from` clause when exporting from
// the local scope). The case keeps NamedExports honest by exercising
// the standalone form, since a regression specific to NamedExports
// wouldn't surface through the import-side tests.
//
//  1. Configure printWidth=20.
//  2. Feed `export { alpha, bravo, charlie };`.
//  3. Assert the rewrite breaks the specifier clause across lines.
//
// @evidence contracts/testing.md#behavioral-verification The print-width rule must break a local named export at width 20 without losing any export name, its order or its terminator. The complete output also detects accidentally adding an import-like from clause.
// @evidence contracts/testing.md#independent-expectations The supported named-list layout breaks these local export specifiers when the complete declaration exceeds the budget. The literal retains the original local bindings and no module source, following the fixture syntax rather than the owning renderer.
// @evidence contracts/testing.md#distinguishing-cases This host owns the overflowing local named-export form, distinct from named imports that carry a module suffix. Short and already formatted targets are covered by the exact-fit and fixed-point hosts; this case is a required transformation.
// @evidence contracts/testing.md#execution-ownership TestFormatPrintWidthBreaksLongNamedExports is a selected public Go unit invoking the owning registered rule and full applied-output helper in one process. Its local export need not resolve actual exported values for syntax-layout verification.
