v0.2.0

Added

• Three dedicated fifty-level campaigns: Magnetic Blocks, Shizen and Arashi, bringing the package to 450 original graded challenges. Exact boards, finite queues, stable IDs, measured difficulty, winning witnesses and deterministic generation are published with the engines.
• Campaign selectors, fixed rule displays, goal progress, replay and next-level recovery in the players.

Fixed

• Clear game-over results and disabled play controls; fixed challenge settings; exact save recovery; responsive goal text; shared cloth and piece appearance; generated API imports and markup.
• Stable board geometry when switching English and Japanese at phone, tablet and desktop widths.

Changed

• CONTRIBUTING.md is the family's one text with a section of its own for Houseki, held to the master in johnmorrisdotca/.github by src/family.test.js; ci.yml and pages.yml are the family's one text (pnpm check, the demo, and the package on Linux, macOS and Windows), and any jobs of the package's own after them.
• The demo's shared stylesheet is demo/houseki.css (it was game.css), named for the package like the family's.
