The canonical Gitea runner is Linux-only, and this package hard-depends on duckdb and httr2 -- both compiled, both with real platform variance -- while having never been checked on Windows or macOS. A large share of the audience is on Windows. Inert here: Gitea reads .gitea/workflows, GitHub reads .github/workflows, so both configs coexist and the Gitea CI stays authoritative for deploys. This goes live the moment the mirror repo exists (#44). The matrix needs no credentials -- setup.R points at the bundled fixture -- which is why that fixture must never be .Rbuildignore'd.
