/* ============================================================
   REPORT / PDF SHEET  —  assets/report.css
   Loaded only by pages that call HOS.report(). Pairs with report.js.

   WHY A SEPARATE SHEET, RENDERED FRESH
   -----------------------------------------------------------------
   The obvious approach — hide the app chrome with @media print and let
   the workspace print itself — produces a printed screenshot of an app,
   not a document. A hospital's reports go to an auditor, a NABH
   assessor, the pollution board or an insurer, so they have to look like
   documents: letterhead, addressee, page numbers, signature block.

   So HOS.report() BUILDS a document into #hosReportSheet and prints only
   that. In print we hide `body > *` and un-hide the sheet, which is far
   more robust than enumerating every chrome class — a new floating
   element added to sim.css later cannot leak into a printed report.

   PRINT IS THE PDF PATH. There is no backend here, and window.print()
   genuinely produces a PDF through the browser's own "Save as PDF"
   destination. A button that toasts "PDF downloaded" and produces no
   file is the kind of thing that gets found during a demo.

   A4 GEOMETRY. 210 x 297mm at 96dpi is 794 x 1123px. With a 14mm margin
   the content box is ~688 x 1017px. report.js paginates against those
   numbers, so if you change --rpt-pad here, change PAGE in report.js.

   COLOUR. Everything uses the --doc-* token family, which exists in
   hos.css precisely for document surfaces: a near-black ink on white
   with its own grey ramp, independent of the app's violet-biased
   neutrals. A report printed in the app's UI greys looks like a
   screenshot; in --doc-* it looks printed.
