/* ============================================================
 * NextGen MIS — Comments & Activity (timeline)
 * ------------------------------------------------------------
 * Re-skins the shared comments-activity partial (the .cs-* hooks
 * are wired to JS, so the class NAMES are preserved — only the
 * look is rebuilt on design tokens). Used on the beneficiary +
 * applicant profiles and the registration list popup.
 *
 * Two parts:
 *   1. Composer — a quiet card: tabs (Take action / Comment), an
 *      action picker (pills), and a note/comment textarea.
 *   2. Feed — a vertical TIMELINE: each entry is an avatar node on
 *      a connecting rail, with author, a tonal source badge, time,
 *      and the comment body. System events read muted; user
 *      comments read in brand colour.
 * Authored in px; semantic tokens; legacy cs- hooks kept as-is.
 * ============================================================ */
