223015b 01-grundlagen: encoding+hex strukturiert — encoding-strang (problem→ASCII→unicode→byte zählen) und darstellungs-strang (WTF!?→8-bit→hex→demos) getrennt statt verschachtelt, 3 brücken-folien (ASCII reicht für englisch / byte für byte als advance organizer / hex ist überall), byte-für-byte demo (3 fenster bin/hex/text mit binärdatei-vs-textdatei-marker), lv-original-vs-fake bild ersetzt leere folie zwischen lossless-titles, 'besser erkennen' → 'besser erkennbar', singular Byte plural in eigener brücke korrigiert
