/**
 * TBB PDF Inserter – frontend viewer styles.
 *
 * "Flat embed" design: no card chrome of its own.
 * The parent theme (.job_description) already provides the card container,
 * so the viewer just renders inline inside it without competing borders,
 * backgrounds, or border-radius.
 *
 * Pages are left-aligned (flex-start) so they sit flush with the card edge.
 * The canvas area uses overflow-x:auto for horizontal scroll when zoomed in.
