/* ============================================================
   DecEptioner — Homepage redesign
   Scoped stylesheet: loaded ONLY on index.html, AFTER style.css.
   New marketing markup uses the `hp-` prefix so it never collides
   with shared classes on other pages. A few existing homepage
   containers are overridden here (safe: this file is homepage-only).
   The live paraphraser tool keeps all its functional ids/classes.
