/* The #printArea print pattern — Phase 4 of REFACTOR_PLAN.md.
   Split out of _shared/base.css in Round 4b so that tools which don't use
   this pattern can still take base.css's layout rules.

   The pattern: the tool builds its print sheet into a container with
   id="printArea" that is hidden on screen, and printing blanks everything
   else so only that container reaches the paper.

   Link this ONLY from a tool that
     (a) has an element with id="printArea", and
     (b) has no #printArea print rules of its own.
   `body * { visibility: hidden }` blanks the whole page and only #printArea
   comes back, so a tool without that element prints a blank sheet. A tool
   with its own @media print block should keep it inline and skip this file —
   see the Phase 4 notes in REFACTOR_PLAN.md for which tools are which.

   Load this BEFORE the tool's inline <style>. The two rules below must also
   stay in this order: they have equal specificity, so the print block wins
   only by coming last. Splitting them across files (or leaving the screen
   rule inline in the tool) silently breaks printing while looking fine on
   screen. */

#printArea { display: none; }

@media print {
  body * { visibility: hidden; }
  #printArea, #printArea * { visibility: visible; }
  #printArea { display: block; position: absolute; top: 0; left: 0; width: 100%; padding: 0; margin: 0; }
