# Fav videos data (/dev only)

`fav-videos.json` drives https://datasystemsglobal.com/dev/fav-videos.html. It is a plain JSON array; cards render in file order.

To add a favourite, append one object to the array (comma between objects, keep it valid JSON):

```json
{"id": "trader-short-slug", "title": "...", "trader": "...", "trader_url": "/dev/trader-x.html#section",
 "upload_date": "YYYY-MM-DD", "duration": "MM:SS", "youtube_url": "https://youtu.be/VIDEOID",
 "thumbnail": "https://i.ytimg.com/vi/VIDEOID/hqdefault.jpg", "notes": ["note 1", "note 2"], "added": "YYYY-MM-DD"}
```

Each card is anchored by `id` (`/dev/fav-videos.html#<id>`). No write API and nothing to rebuild; nginx serves /dev JSON with `Cache-Control: no-cache`.
