1. Run the site with python3 serve.py in the visual-journal folder, then open http://localhost:4321/studio.html.
2. Fill in the details and build the media flow from photo / note / video / divider blocks.
3. Publish — your photos save into images/<slug>/, native clips into videos/<slug>/, and the entry is added to content.json. No folder picker, works in any browser.
4. Open the site to preview. When you're happy, redeploy (drag the folder to Netlify, or push to git).

For real short films, prefer a Vimeo/YouTube link — it keeps the site fast. Use video files only for small clips.

If you opened the site with the plain file server instead of serve.py, the indicator up top says “Publish will download” — Publish then downloads your media + copies the entry JSON to paste into content.json yourself.
