/* working-papers-print.css
 * Shared browser-native print stylesheet for the /working-papers series,
 * identical across all 6 sites. Owned by project-design; content-wise built
 * from the real, proven techniques in financial-report-layout (this vault's
 * WeasyPrint compliance-document recipe), adapted for browser-native
 * window.print() + @media print rather than server-side PDF generation, and
 * for prose/figure/occasional-table content rather than dense financial
 * tables.
 *
 * Usage: link this file on every /working-papers page, in addition to the
 * site's own normal stylesheet. It only takes effect inside @media print —
 * it does not affect on-screen rendering and requires no other integration.
