/*
 * STRATEGIES-HUB-WP-01 — /estrategias/ quantitative strategies pillar/hub.
 * Reuses the shared, sitewide `.smq-course-*` primitives already established by
 * course-amibroker.css (hero shell, section rhythm, eyebrow, CTA, evidence frame, FAQ pattern) --
 * those are DS-002 page-level components and are NOT redefined here. This file adds only the new,
 * hub-specific classes (`.smq-hub-*`) needed to give this pillar its own editorial/authority
 * identity, distinct from the product pages (Momentum) and course pages (AmiBroker, Pairs).
 *
 * IMPORTANT: does not reuse the `.smq-estrategias-*` prefix already used by Home's own
 * `#strategies` section (assets/css/strategies.css) -- that is a different page (Home), a different
 * component, and must not collide with this one.
 *
 * Same overflow-safe grid discipline (minmax(0, Nfr) + min-width: 0) applied from the outset.
