32 klassische Skripte in der alten Reihenfolge (01-core … 99-init), ohne Änderung am Code darin: geschnitten nur zwischen Anweisungen, je Datei 'use strict' wie vorher für die ganze Datei. Geprüft (acorn): kein Code, der beim Laden läuft, braucht einen Namen aus einer späteren Datei. Globale Funktionen und let/const bleiben global, die App-Schichten (native.js, native-eink.js, …) umhüllen sie wie bisher. Template und sw.js-SHELL listen die Dateien; diora-android build_web nimmt static/js rekursiv. Getestet: 14 Browser-Tests (e2e), Desktop-App (Buch, Lesestand, Leiste im Reader, Hell/Dunkel).
