   Scope:
   - Intended for individual essay/article pages.
   - Handles typography, media, forms, and content links.
   - Navigation, header, footer, and layout live elsewhere.
   Notes:
   - Variables duplicated here by design for portability.
   - Avoid adding component/layout rules to this file.
