Function load_layout 

pub fn load_layout(name: &str) -> Result<ScreenLayout, RenderError>

Load a layout by name from the game’s data directory.

Tries to load from data/ui_layouts/{name}.json relative to the current working directory (a generic fallback; callers that know their own data root pass a full path instead).

Errors

Returns RenderError::InvalidLayout if the file cannot be read or the JSON is malformed.
