/* ──────────────────────────────────────────────────────────────────
   Print stylesheet — force light theme regardless of [data-theme]
   ──────────────────────────────────────────────────────────────────
   Without this block, printing (or "Save as PDF") while in dark
   theme produces near-invisible light text on white paper: the
   browser strips background colors for ink-saving but keeps the
   text color, which in dark mode is a near-white #f1f5f9. The
   result is unreadable on paper.

   Fix: reset every dark-theme CSS variable to its light counterpart
   inside @media print, and force html/body back to dark-on-white.
   This auto-applies to every JSP that loads dark-mode.css, so the
   worksheet engine, math calculators, biology tools, and any future
   tool benefits without per-tool changes.

   Also kills CSS transitions/animations during print — Chrome
   occasionally snapshots mid-transition states which prints weird. */
