/* ── notebook.css — shared notebook-style system across all pages ──────
   Loaded after page-specific CSS so the notebook system is the lowest
   common denominator. Used by: index.html, about.html, contact.html,
   writing/*.html, and (lightly) case-study pages.

   Visual language: white paper, polaroid-style cards, slight rotation,
   Caveat handwriting for personality, Inter for substance, Lora for
   italics. No border-radius anywhere (square corners, deliberate).
