8935f31091 rework 223015b chapter 1: analog/digital narrative arc 
replace flat analog-vs-digital slide and sampling overview with
four-slide narrative: schallwelle → abtastung → digitales ergebnis
→ zurück zu analog (dac). builds a causal chain from sound wave
through digitization back to playback.
