 *   If pull requests include user-visible changes, the "developer" version number should be increased (e.g. from 0.10.1.5 to 0.10.1.6). This ensures that `easystats::install_latest()` will download the latest versions.

Do not use `library()` or `require()` at the top of a file (no full import, only selective import of functions). However, in test files, package vignettes (.rmd), or in the package documentation, `::` is not required for core R packages like `stats` or `tools`.
 *   **Conditional Checks:** Use `insight::check_if_installed("pkg_name")` to check if a package is available before using it, especially for optional ("Suggests") dependencies.
 *   **Argument validation:** Use `insight::validate_argument()` instead of `match.arg()` to validate correct input of arguments, unless you need `several.ok`. In this case, rely on `match.arg()`.
