/* ---------- Print: isolate whichever modal is currently open ----------
   Shared by every "Preview / Print" flow (quotations, invoices, purchase
   orders, documents). Hides the app shell and every OTHER modal-backdrop
   via display:none (removes them from layout, so the printed content
   starts at the top of the page) and resets the open modal's own
   fixed/flex/centering positioning to static so its content flows as one
   normal in-page block — a `position:fixed`/`absolute` ancestor spanning
   content taller than one printed page is what causes a browser to
   misplace/overlap content across the page break.
   Written once here (rather than per document-type stylesheet) because
   those stylesheets all load globally — per-file rules scoped to a
   specific modal id via `:not(#thatId)` end up matching every OTHER
   preview modal too, and whichever stylesheet loads last wins the tie,
   hiding whichever preview you actually meant to print. `.modal-backdrop:
   not(.open)` / `.modal-backdrop.open` are mutually exclusive, so there's
   no specificity race between them. */
