Build a small read-only forum called Field Notes.
Use these three fictional topics in this order:
- Build a small lighthouse | Builds | Lina | 12 replies
- Sort a chest with two hoppers | Automation | Moss | 7 replies
- Plan a village path | Builds | Rowan | 4 replies

Keep each title, category, author and reply count unchanged.
Add All topics, Builds and Automation filtering.
Make each topic open a short read-only description.
Offer Paper and Block-world themes using original artwork.
Changing the theme must preserve the selected category and topic data.
Reset must restore all three topics and the Paper theme.
Do not add accounts, posting or editing controls.
At 390px, keep the controls and reply counts readable without page overflow.
Deliver the project files, run instructions and a short check report.
