Drop a [[files]] marker into any Markdown file and let this GitHub Action replace it with a directory tree. Choose the look:
ascii — the classic tree block, with optional aligned descriptions.
svg — a crisp SVG with folder icons that matches GitHub's light/dark theme and scales responsively.
collapsible — a GitHub-native, expand/collapse <details> tree.
