 * FM-DATA-TABLE.CSS
 * ====================================================================
 * Handy-Tabelle (Baustein B2 aus doc/uiux/MOBILE-UX-KONZEPT.md), Variante „Kennzahl“.
 * Ein einziges <table>-Markup, alle Spalten bleiben im HTML:
 * - Handy/Tablet (< 992 px): Zeilenliste „Platz · Verein · eine Kennzahl“, Chips wählen die Kennzahl,
 *   eine Zeile klappt alle Werte auf. Kein seitliches Wischen, kein Scrollkasten.
 * - Desktop (ab 992 px): klassische Tabelle, Spaltenkopf klebt unter der festen Kopfzeile.
 * Verhalten: js/fm-data-table.js. Mobile-first, Erweiterung nur per min-width.
