serveStatic() — serve files from public/ before your routes:
this.use(serveStatic());
this.use(serveStatic({ root: "./assets", maxAge: 86400, immutable: true }));ETag / Last-Modified / 304, Cache-Control, dot-file policy (ignore/deny/allow), per-file headers, and path-traversal protection. node:fs is loaded dynamically so the core still imports on the edge. See docs/static-files.md.
