/* ============================================================================
 * sidebar-module.css — Study Sidebar styles for embedding on non-Reader pages
 * ----------------------------------------------------------------------------
 * Extracted subset of public/assets/app.css covering only the selectors the
 * study-panel / word-study / commentary / cross-ref / bookmark / note UI
 * actually needs. A host page that already links app.css does NOT need this
 * file; it only exists so the Sermon Notes page (and similar) can opt out of
 * the 8k-line app.css.
 *
 * The selectors here are structured into named sections so future extractions
 * can add or remove chunks without hunting.  Rules are copied verbatim from
 * app.css; when app.css changes a matching rule, update here too.
