Brain-edit-slides

Add a Canva-style visual Edit Mode to any HTML presentation/slide deck. Use this skill EVERY TIME you create, generate, or finish building an HTML presentation, slide deck, or מצגת for the user - inject the editor automatically as the final step. Also use when the user asks to "make my deck editable", "add edit mode", "הוסף מצב עריכה", "תעשה שאוכל לערוך את המצגת", or wants to move/edit/add elements in an existing HTML deck.
