## Description

<!-- SECTION:DESCRIPTION:BEGIN -->
Create a validation plan or tests for CLI flag behavior, stream resolution, and subtitle precedence/fallback rules so streaming mode changes are measurable and regressions are caught.
<!-- SECTION:DESCRIPTION:END -->

## Acceptance Criteria
<!-- AC:BEGIN -->
- [ ] #1 Document/manual checklist covers `-s` and `--stream` invocation and streaming-only behavior.
- [ ] #2 Include cases for (a) stream with JP subtitles, (b) no JP subtitles with Jimaku fallback, (c) primary-language not Japanese.
- [ ] #3 Run or provide reproducible checks to confirm non-streaming behavior unchanged.
<!-- AC:END -->

## Implementation Notes

<!-- SECTION:NOTES:BEGIN -->
