   PHUE COMPONENTS (Atoms)
   ---------------------------------------------------------
   RULES FOR EXPANSION:
   1. Purpose: Low-level reusable UI controls and elements.
   2. Scope: Buttons, Inputs, Badges, specialized Text styles.
   3. Composition: Combine multiple properties to form a coherent UI object.
   4. States: Must include :hover, :focus, and [disabled] states.
   5. Naming: .phue-[component]-[variant] (e.g., .phue-button-primary).
