/* Paper landing page — the classical layout for externally-originated research.
   First use: Waltzman, "The Decision Environment" (Susan's Option 1 mockup, 2026-08-27).
   Distinct from paper.css (the in-house flash-paper reading system): this layout is
   summary + sidebar, built for papers whose full text lives in the PDF. */
