+notes:
+- Japan nationwide aoi-complete: z0-z4 在 1:20M 不覆盖日本南部时允许回退 1:3M；不改变 z5-z12 细节策略。
+- Japan full-detail production 仍保持 z0-z12；不新增 z13/z14。
+- z12 enumeration 加入 1:7,500（G），避免正确 Japan 数据中的 G 级细节被生产策略直接忽略。
+- z12 scale ladder 优先 7,500，再回退 20k/50k/100k/...。
+- z0-z11 extent=4096；z12 extent=1048576，保持已验证 NavSea/MapLibre 契约。
+- enumeration_scales 仅决定物化范围；scale_ladders 仅决定 tile 内选择/回退。
