v1.3.0

Added

• Cheatsheets: Every course has a one-page recap, written back over the transcript as the points worth remembering rather than a summary of what each section covered. Definitions, figures and the mistakes the speaker warns about, one line each, with a timestamp that opens the video at that moment. It is written in the background while the course is generated, so it is waiting by the time it is wanted, and it saves as an image or a PDF on Parcourse paper.
• Forgetting a Concept: A concept can be dropped from your knowledge graph without touching anyone else's. Forgetting one asks first, and names everything that goes with it, since a topic without its field has nothing left to hang from.
• Only YouTube Links: The bar on the home screen takes a YouTube link and nothing else. Anything else is refused as it is pasted, and every shape YouTube uses is accepted: watch, youtu.be, shorts, embed, live, and the mobile and music subdomains.
• Changing Servers: A deployment behind the VPN no longer gives up the first time YouTube turns it away. It asks for a different server and tries again, waiting less on each attempt, and only says so once the reconnects run out. VPN_ROTATIONS sets how many, and zero keeps the old behaviour.

Changed

• The development branch and image is now the more cutting-edge set of features while main and latest are more about stability.

Fixed

• Deleting a course no longer strands the concepts around it. Anything a surviving concept still belongs to is kept as well.
• A concept on the knowledge graph can be clicked without being dragged out of place, and carries a ring under the pointer so it reads as something to click.
• The generation pills are back to the look the dark theme accidentally changed.
