- Default `npm run build` now produces a root-relative build (CF Pages
custom domain at loto.miti99.com). The /loto basePath is opt-in via
`npm run build:gh` for the rare manual GH Pages export.
- Removed both GitHub Actions deploy workflows (.github/workflows/) and
the dangling `build:cf` script (it was identical to `build` after the
default flip).
- next.config.mjs: simplified basePath logic — only `BUILD_PROFILE=gh`
toggles a non-empty path; everything else (CF, local dev) is root.
