// Standalone tests for reasampler::readFileBytes — no REAPER, no framework.
// The ONE whole-file loader (Q-W1, T2-03) shared by both artifacts. Exercises
// the three-way contract: exact bytes back, empty on a missing file, empty on
// an empty file. Uses a scratch file in the test's working directory.
