/* A MOMENT SNAKE AND CHESS · HÄUTUNG DES AUGENBLICKS (2026) — Projektseiten · medienwerkstatt006
   Gestaltungsprinzip: der Augenblick als Brett. 8 × 8 Felder = 64 Frames = 2,56 s.
   Schwarz / Weiß als Haut, Farbe darunter (Häutung). Das Lid (Mandelform) öffnet und schließt den Blick.
   Jeder Abschnitt ist ein Feld (a1 … h8), jede Zeitangabe ein Frame. */
