SYNTHETIC QA ONLY — programmatic publishing route verification

This is a clearly synthetic QA article created only to verify the complete programmatic publishing path. It is not research, advice, or production content.

The still image verifies independent PNG upload, Markdown construction, reader-facing alternative text, and caption rendering.

The four-frame animation verifies that a genuine animated GIF is uploaded independently and remains animated when rendered by the QA frontend.

If you can read this paragraph, the one-shot published post payload and ID-based API verification both completed successfully.
