/*
 * Version 3 -- Reports workspace, on screen and on paper.
 *
 * Two presentations of one document. The screen rules build a configuration
 * form beside a live preview; the `@media print` block at the end strips the
 * application away and lets the same markup flow onto pages. No second
 * renderer, no canvas, no image -- what prints is the semantic HTML the
 * preview shows, which is the only way the two can be guaranteed to agree.
 *
 * Nothing here is coloured by outcome. A report has no governed status to
 * express, and `MISSION_CONTROL_SPEC.md` §7 forbids an unexplained colour
 * anywhere in this application.
 */

/* ---- panel width --------------------------------------------------------- */

/*
 * The shell caps a panel at 760px, which suits a form and a short prose page.
 * A report is a document with a wide table -- a hundred athletes across five
 * systems -- and at 760px it rendered into a narrow column with two thirds of a
 * desktop viewport left empty. Widened here rather than in the shell, so no
 * other page's layout changes.
