/* ==========================================================
   Church History Timeline — Mobile List View — touch-first row list, scrub rail, and mode-mobile overrides
   Part of the split stylesheet (see css/ for the rest): base.css,
   top-bar.css, datasource-filters.css, map-view.css, side-panel.css,
   article-view.css, mobile-view.css. Loaded as separate <link>
   tags in index.html; order barely matters for CSS (later same-
   specificity rules win, and there are no same-selector conflicts
   across these files) — base.css is simply listed first as a
   convention, since it holds the shared :root variables and button
   primitives (.btn, .jump-btn, .read-article-btn, .google-search-btn)
   the other files build on.
   ========================================================== */

/* ==========================================================
