based on Lagopus
Demo https://r.tiye.me/WebGPU-Art/roller-coaster/ .
本轮迁移到正式 Calcit/procs 0.31.0，使用已发布的 Lagopus 0.5.13、Quaternion 0.2.17、Memof 0.0.41 和 JS FFI 0.2.7。原 2,000 个方块、10,000 个轨道采样、40 秒相机周期及 hud! 页面报错保留；不减少场景复杂度、不更改 shader 或原前端部署路径。
旧 Ref/Option 写法迁移到 defref 和 Option :some/:none；地面范围保留 -99…99 的原顺序。备用 cycloid 路径中的三维 List 改为显式读取三个坐标生成 JS 数组，避免无证明展开；不改变坐标计算或相机更新顺序。原导入声明去掉多余 []，CI 从 deps.cirru 读取工具链并增加完整 strict。
本地全定义与完整 strict、生产构建通过；实际 WebGPU 页面显示地面、方块与轨道，相机持续推进，浏览器 warning/error 为空。备用 cycloid 路径没有单独浏览器验收，不声称全部相机路径或热重载生命周期均已覆盖。没有放宽类型门禁或基线，没有新增验证脚本。
Uses Calcit 0.31.0, Node 24 and Yarn 4.18.0. Source and formal
dependencies are declared in calcit.cirru and deps.cirru.

yarn viteGeometry and camera calculations use quaternion.vector/V3. The original
2,000 cubes, ground grid, 10,000 rail samples and 40-second camera animation
are preserved. Reloading cancels the previous animation frame before restart.
The unused template :states handler is retired; :tab has a typed Op contract.
CI checks and builds PRs without deploying them. Main uploads frontend resources
to https://cos-sh.tiye.me/WebGPU-Art/roller-coaster/; setting the COS action's
public-base-url enables its built-in per-file checksum verification. The original
page deployment path /web-assets/repo/${github.repository} remains unchanged.
Generated js-out/ and local install state are not tracked. compact.cirru
and package.cirru are retired.
The touch-control npm package currently only publishes 0.0.4-a1 as latest;
it is pinned exactly, not to a floating prerelease range.
