/*
 * 984_base64_run — execute the lib/encoding/base64 @test fixture
 * under the C-side `ww run` driver and assert exit 0.
 *
 * Sibling to 980_memio_run / 981_temp_run / 982_getopt_run /
 * 998_bufio_run. base64_test.ww carries its own `export fn main()`
 * that drives the @test fns and signals which case failed via the
 * exit code, so this file is just a thin wrapper — no @test
 * scanning, no synthetic main generation.
