WordPress „Zusätzliches CSS“ (in Divi „Eigenes CSS“) über die Design-Pipeline: Probelauf mit Zeilen-Diff, design_rev, Bestätigung, Snapshot, Rollback und Wiederherstellen (Bereich custom_css). Der Guard lehnt </style, <script, expression(, javascript: und neue @import ab und warnt bei fremden Hosts; nur Neues zählt, Bestehendes blockiert keine Änderung. Erfordert edit_css und die Divi-Rolle Theme-Anpassung. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
