/* Step Up AVL — "The Broadsheet", research layer.
 *
 * Companion to assets/broadsheet.css (which must load first: this file uses its
 * tokens, its shared shell, and .page-head / .kicker / .standfirst / .btn-outline).
 *
 * Spec: _docs/design/broadsheet-2026-07/DELTA-v14-research-pages.md.
 *
 * Two pages:
 *   /research         the explainer. A LANDING page, not an article: cream
 *                     background, no charcoal surround, no sheet, no drop cap.
 *   /research/library the source directory. Generated by
 *                     _docs/research/insecurity-resource-library/build_library.py,
 *                     which links this file. A reskin only: the search box, the
 *                     four selects, the live count, and the card data all behave
 *                     exactly as they did.
