## Overriding settings
Define a `projectSettings` attrset and pass it as the second module in `evalModules`. Every option in `nvimConfig.wrapperConfigs.default` can be overridden here.
Define a `projectSettings` attrset and pass it to `nvimConfig.lib.eval` or `nvimConfig.lib.mkWrapper`. The helper injects your overlaid `pkgs` automatically, so downstream consumers do not need to wire `specialArgs` themselves. Every option in `nvimConfig.wrapperConfigs.default` can be overridden here. Local `packages.default`, local `devShells.default`, downstream helper usage, and `pkgs.vv` all resolve the same module defaults unless you override them.
### Basic downstream flake example
This example enables a few cats, adds runtime tools to the shared wrapper/devShell package set, and appends language libraries to the default Python and R environments.

Override `catPkgs` to add tools that appear in both the wrapper PATH and the devShell. To add always-available packages not gated by any cat, use `runtimePkgs` directly (see next section).

### Choosing the right override surface
- Use `cats` to enable or disable a whole language or tooling category.
- Use `settings.lang_packages` to add or replace Python, R, or Julia libraries within a language environment.
- Use `catPkgs` to change the full runtime tool list for a category. `config.runtimePkgs` drives wrapper PATH composition, while `nvimConfig.lib.devShellPackages config` returns the package-only list suitable for `mkShell`.
- Use `env` or `envDefault` for wrapper environment variables.
- Use `specs` for plugin additions or custom runtime behavior.

- **Overlays** (`overlays/`) inject base packages into nixpkgs (rWrapper, quarto, baseRPackages, basePythonPackages).
- **Overlays** (`overlays/`) inject dependency package sets into nixpkgs (`rpkgs`, `baseRPackages`, `basePythonPackages`, plugins). Top-level `rWrapper` and `quarto` are compatibility conveniences, but `pkgs.rpkgs` is the canonical R surface for downstream configuration.
- **cat-packages.nix** is the single source of truth for per-category packages. Each list is gated by its cat toggle.
- **deps.nix** wires `catPkgs` into the wrapper's runtime PATH.
- **flake.nix** reads `catPkgs` for the devShell. `langPackages` feeds into `settings.lang_packages`.
- **settings.lang_packages** holds the shared defaults used by local outputs and downstream module consumers.
- **flake.nix** exports `lib.eval`, `lib.mkWrapper`, and `lib.devShellPackages` as the canonical downstream helpers, and builds `packages.default` and `devShells.default` from the same module config.
