/*
 * RESEARCH-HUB-WP-01 — /research/ Research pillar/hub (recuperado de website-production/
 * research-hub-wp01r1, commit 843fd01, donde el archivo se llamaba informes-tecnicos-hub.css y la
 * URL histórica era /informes-tecnicos/; renombrado aquí para coincidir con nuestro slug local
 * /research/ -- ver el comentario de procedencia en page-research.html para el conflicto de URL
 * documentado). Reuses the shared, sitewide `.smq-course-*` primitives (course-amibroker.css) AND the `.smq-hub-*`
 * components already established by the Strategies/Formación hubs (concept chips, numbered
 * step-flow, dark final-nav bookend) — these are already DS-002 page-level components, loaded
 * globally by functions.php, and are intentionally reused here. This file adds only the new,
 * Research-specific classes (`.smq-rhub-*`) needed for this page's own identity (the library-style
 * Hero visual, Latest Research cards, the tiered Area hierarchy, Series cards, the Free Research
 * empty state, and the Membership panel).
 *
 * IMPORTANT: does not reuse `.smq-research-*` / `.smq-latest-research-*` (Home's own "Últimas
 * Research" section, in latest-research.css) or `.smq-membership-*` (Home's own Membership section,
 * in membership.css) — those are different pages/components and must not collide with this one.
 *
 * Same overflow-safe grid discipline (minmax(0, Nfr) + min-width: 0) applied from the outset.
