/* ---------------------------------------------------------------------------
   The books are guarded.

   Owner, 2026-08-10, on the solved volume: "disable copy pasting and all things
   possible so we safeguard ourselves from copycats". Owner again, 2026-08-22,
   on the written notes: "as of now i was able to copy paste the text from the
   notes pages ... i dont want any user to be able to do that, so they will
   instead spend time here on the website, and read". The ordinary way out of a
   web page is closed on both: no selection, no long-press sheet, no drag,
   nothing on the printed sheet.

   ⛔ ONE SOURCE. This began as a block inside assets/css/qp-solution-page.css
   with its twin script inline in pages/core/qp-solution.php, and covered the
   solved volume alone. The written notes needed the same guard, and a second
   copy of a hundred lines is how a guard silently dies: one page gets a fix,
   the other does not, and nobody finds out until a reader copies a chapter. The
   rules live here, the behaviour lives in assets/js/copy-guard.js, and
   includes/copy-guard.php is what a page calls.

   ⚠️ BE HONEST ABOUT WHAT THIS IS WORTH. Every word of both books is in the
   HTTP response, because both are meant to be read by Google and quoted by
   Claude and ChatGPT (project_ai_crawler_posture), so anyone who fetches the
   URL without a browser has the whole thing whatever this file says. What is
   closed here is the route a copycat actually takes, which is select, copy,
   paste. It raises the cost; it is not a lock, and it must never be sold
   internally as one.

   ⛔ SCOPED TO THE READING SURFACES, and nothing here may reach past them. The
   crumb, the navbar, the footer, the search box and the ads all behave normally:
   a site that will not let you right-click is a broken site, not a protected
   one. Two roots today:
     .qps-page  the solved question-paper volume
     .mn-notes  the written notes book, both the whole book and one chapter
   .mn-guarded is the hook a third surface should use rather than adding a
   fourth class name here.

/* Print, and print-to-PDF with it, is the fastest way to lift a whole book, and

   (project_view_only_2026_07_15). It is also the first thing a reader reaches
   for once the clipboard stops answering, so closing the clipboard without
   closing this would buy very little. The sheet that comes out carries the
   imprint and nothing else.
