/**
 * Linguistics Hub
 * Page-specific styles for the multidimensional Linguistics navigation hub.
 * Scoped under the body class page-hubs.php adds (.linguistics-hub-page).
 * Loaded after the shared hub CSS stack (_base, _hub-shared, hub-topic).
 *
 * Design: aligned to the native itako-dict hub aesthetic — one warm wood accent,
 * serif titles, thin rules, modest radii, gentle hovers. No per-view color
 * coding, no decorative dot hero, no badge pills.
