Modules

Stackpanel ships with a set of builtin modules that provide integrated tooling for common development workflows. Each module is a directory under nix/stackpanel/modules/ with a standard structure:

meta.nix — Pure data: name, description, icon, category, tags, feature flags, flake inputs
module.nix — Options and configuration logic
ui.nix — Studio panel definitions
default.nix — Entry point that imports the above

Modules are auto-discovered — drop a new directory into nix/stackpanel/modules/ and it's available immediately.

For fast metadata access without full Nix evaluation:

config.stackpanel._moduleMetas.<module-id>
