/* P25X Live -- History tab (js/tab-history.js). Builds on app.css (.panel, .ph, .ph-row, .range, .stats, .stat, .empty).

   ANIMATION AUDIT: none. No animation, no transition, nothing that moves or flashes; the bars are static SVG rects
   and width-set divs. (The tab change itself may cross-fade through a View Transition, see js/main.js; that is
   off under prefers-reduced-motion and the Reduce motion button.) */
