Summary

Resolves #19

Entfernt jQuery 3.7.1 (CDN) und die ungenutzte Masonry.js-Datei. Der gesamte JavaScript-Code (~130 Zeilen) wurde in Vanilla JS neu geschrieben.

Changes

  • js/haus-schleusingen.js: Komplett neu in Vanilla JS
    • Navbar-Scroll: window.addEventListener statt $(window).on
    • Hero-Animation: classList.add statt addClass
    • Scroll-Animationen: IntersectionObserver statt scroll-Event (performanter)
    • Akkordeon: display-Toggle statt slideUp/slideDown
    • Lightbox: Native Event-Listener statt $(document).on
    • Formular: Native value/addEventListener statt jQuery-Methoden
  • haus-schleusingen.html: jQuery CDN <script>-Tag entfernt
  • js/masonry.pkgd.min.js: Gelöscht (wardead code)
  • eslint.config.js: jQuery-Globals entfernt

Performance-Gewinn

  • ~30KB weniger (jQuery CDN + Masonry)
  • IntersectionObserver statt scroll-Event
  • Keine externe Abhängigkeit mehr

Testing

  • Alle 6 Funktionsbereiche auf Funktionsparität geprüft
  • Kein jQuery-Reference verbleibt im Code
  • Review: APPROVED
