Where this is stored

• This browser: Mark as read saves to this browser's local storage for this site. Nothing is sent anywhere. It does not follow you to other browsers or devices, and it is lost if you clear site data or use a private window.
• The repository: lessons recorded in curriculum/PROGRESS.json show as read on every device, once the site is published. This is the durable record.

Keep it or move it

To make progress permanent: export it, give learning-progress.json to your AI coding assistant, and ask it to "merge this into curriculum/PROGRESS.json following prompts/UPDATE_PROGRESS.md". Then commit and publish. To move to another device: export here and import there.

Start over

This only clears marks stored in this browser. Records in curriculum/PROGRESS.json can only be changed in the repository.
