How does the drag-and-drop form builder work?

The form builder uses a document-style canvas that looks and feels like writing a document:

• Each field appears as a card - hover to reveal a drag handle on the left for reordering
• On the right of each field: a gear icon (advanced settings) and a trash icon (delete)
• Between fields, a "+" button appears on hover so you can insert new fields anywhere
• At the bottom, type a question directly (press Enter to create a text field) or type "/" to open the slash command menu
• Click directly on field labels and placeholders to edit them inline
• Click the red asterisk (*) next to any label to toggle required/optional
