First release.

Claims that cost rent and shrink instead of vanishing. Your newest claims lapse first, your home base is last, a lapsed claim keeps protecting at full size through a week's grace, and nothing is ever deleted. Paying restores everything instantly at full size. A player with one claim is never evicted from it.

Claims are a radius around a block you place rather than chunk rectangles.

Paper 1.21+. No dependencies, no database, no economy plugin needed.
