 ** hyprscrolling
 This Nix module integrates the hyprscrolling plugin into a Home-Manager managed Hyprland setup in a declarative and reproducible way. It ensures the plugin is installed, optionally switches Hyprland to the scrolling layout, and renders user-defined plugin settings directly into the Hyprland configuration. The goal is to manage the scrolling workspace behavior entirely from Nix instead of maintaining manual edits inside hyprland.conf.
