Eleventy‑plugin‑bundle is a lightweight asset bundler built into Eleventy that lets you create per‑page or site‑wide bundles of CSS, JavaScript, SVG, or HTML directly from your templates. It provides shortcodes (`{% css %}`, `{% getBundle %}`, `{% getBundleFileUrl %}`, etc.) to collect code snippets, optionally bucket them (e.g., critical vs deferred), apply custom transforms, and output either inline code or hashed files—making it ideal for Eleventy users who want a simple, fast alternative to full‑blown bundlers for tasks like critical‑CSS, SVG icon libraries, or head‑element injection.
