/* ==========================================================================
   Boss Writer — Bhaskar Yadav
   Design concept: "Ledger & Ink" — a science notebook meets a comic
   artist's drafting table. Cool graph-paper background, hairline navy
   ink borders, one hot marker-orange accent used like an editor's pen,
   and comic-panel cards (the page's one signature move) for anything
   that represents a made thing: an article, an artifact, a link out.
