// ─── NOTES ───────────────────────────────────────────────────────────────────
// 1. Use tidyverse:4.4 not tidyverse:4.4.2 — the patch tag does not exist for
//    devcontainer images and will cause an immediate build failure.
//
// 2. Keep this file minimal. Do not add onCreateCommand or postCreateCommand.
//    Claude Code handles package installation interactively — baking it into
//    the container build causes long, opaque build failures.
//
// 3. Do not add the Python devcontainer feature. If the project uses Python
//    (e.g. via reticulate), Python is managed inside the R package virtualenv.
//    Adding Python as a system feature causes path conflicts.
//
// 4. Do not add RENV_PATHS_CACHE. The default path does not exist in the
//    container and causes renv to fail silently.
//
// 5. If your project needs additional VS Code extensions, add them to the
//    extensions array above.
//
// 6. Replace "your-repo-name" with the actual repository name.
//
// See CODESPACE_SETUP.md for full setup instructions.
