/**
 * SETTINGS-SEMANTIC QA sweep -- EXTENDED: covers tools NOT in settings.qa.spec.ts.
 *
 * For each tool we vary settings, process, download, and assert the output
 * changed as expected via decode oracles (imageInfo, imageLuma, imageSaturation,
 * probeMedia, mediaDuration, magicMatches). Where a setting's effect is NOT
 * decode-verifiable, we confirm "valid output + no crash" and label it honestly.
 *
 * Run:
 *   pnpm playwright test --config tests/qa/playwright.qa.config.ts \
 *       tests/qa/settings-extended.qa.spec.ts --workers=1
