/* Performance-Heatmaps auf der Makro-Seite (Ä-68, macro/_heatmap.html): Megasektoren und
   Sektoren nebeneinander, darunter die Industrien in aufklappbaren Gruppen (≤ 1100 px alles
   untereinander). Formensprache der Marktampel: kleine Gruppenüberschriften, ruhige Kacheln mit
   Abstand statt Trennlinien. Zellfarbe divergierend aus den Richtungsfarben (DESIGN 2.3:
   Verlust --neg, Gewinn --pos) in vier Stufen je Richtung, neutral um 0; die Zahl steht immer in
   der Zelle, der Text bleibt --text-1 auf allen Stufen. Grau: zu wenige Aktien. */
