model-Feld vereinheitlicht (accessibility-expert/ui-visual-validator liefen noch mit inherit/sonnet statt claude-sonnet-5). Überschneidung accessibility- expert vs. ui-visual-validator entschärft (Code-Audit vs. reine Screenshot- Beurteilung, gegenseitiger Verweis). ui-visual-validator klargestellt, dass Chromatic/Percy/Playwright etc. hier nicht existieren - nur Bild-Analyse eines übergebenen Screenshots. tailwind-expert korrigiert (Tailwind v4 ohne tailwind.config.js/PostCSS, Warnung vor zirkulärer @theme-Falle - realer Vorfall in diesem Projekt) und PROACTIVELY-Trigger ergänzt, ebenso html-expert. css-expert von tailwind-expert abgegrenzt (plain CSS vs. Utility-Klassen).
