/* ProHRHQ public research library. Keep page-specific styles isolated here.
 * CHANGE LOG
 * File: static/css/prohrhq_library.css
 * Purpose: The few additions https://prohrhq.com/library/ needs on top of
 *          static/css/carrier_tools.css, whose layout it reuses as-is (hero, jump buttons,
 *          category sections, picture cards, buttons).
 * How it works: .lib-more is the second link under a card's button (phone version, full paper,
 *          PNG); .lib-links is the link list on outside-research cards; the picture cursor
 *          shows it opens full size in the sitewide lightbox.
 * 2026-10-23 - Business-area picker: .lib-area tiles (area picture, name, one line, count), the
 *              .lib-bar switcher, focus headings, card titles as h4. .lib-js (set by
 *              static/js/library_areas.js) shows one area at a time; without it every area shows.
 * 2026-10-14 - Reduced to additions only; the page now uses the Carrier Tools layout (Michael).
 * 2026-10-14 - Mockup grid, panels and compact cards (superseded the same day).
 * 2026-10-04 - Small "See Carrier Tools" button on each research paper card.
