Workflow: select a site -> automatically fetch and area-prorate the use-zone designation from Japan's National Land Numerical Information (A29) -> automatically search realistic building placements that satisfy road slant limits, neighboring-lot slant limits, floor-area ratio, building coverage ratio, and daylight/shadow regulations (including regulations triggered when the shadow falls on a neighboring regulated zone) -> export the results as a QGIS layer, JSON, and HTML. Version 0.2.0 upgrades the search from \"maximize floor area only\" to a practical multi-objective placement search: rotation angles are discretized to the site's own boundary directions, buildings are anchored against the site boundary instead of floating in the middle, and candidates are ranked by a combined score (floor-area ratio, usable open space, south-facing daylight) with near-duplicate results pruned. The HTML output now also shows a breakdown across multiple use zones and which shadow-regulation zone applies. It connects to the existing browser tool \"\u65e5\u5f71\u56f3\u30fb\u9ad8\u3055\u5236\u9650\u30c1\u30a7\u30c3\u30ab\u30fc\" (Shadow Diagram / Height Limit Checker) via JSON (hikage-checker format), so a search result can be opened directly in that tool to check shadow diagrams and sections.
