In edit mode with canEditEngagements, wraps [form | C2ConfigCard] in a lg:grid-cols-2 responsive grid with items-start alignment. Stacks to single column on screens narrower than lg. In create mode, retains the existing max-w-2xl single-column layout. No logic changes. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
