What is feature-image?
Generate a branded social media image announcing a new feature or update. Analyzes git history, auto-detects brand from codebase (Tailwind, CSS vars, design tokens), replicates UI elements, and captures via Playwright. Use when the user wants to create an announcement image, says 'feature image,' 'announcement graphic,' 'social image for feature,' or wants to visually announce a code change.
