Catch-all routes ~ tutorial ~ implement

A [param] directory matches exactly one segment. To match one or more trailing segments — a docs tree, a file browser — prefix the name with ...:

src/routes
    docs
        [...path]
            page.ts       -> /docs/a, /docs/a/b, /docs/a/b/c, ...

The matched segments surface as a single readable, joined with / — visiting /docs/guides/routing gives params.path the value "guides/routing".

A catch-all must be the last thing in its path: nothing can route below it. And when routes compete for the same URL, static segments beat [param]s, which beat catch-alls — so you can add a docs/page.ts later without the catch-all swallowing it.

Your task

The home page links into /docs/..., but the docs tree doesn't exist yet.

Create the file src/routes/docs/[...path]/page.ts in the file tree — one [...path] directory catches every depth.
Default-export a page that renders params.path so it shows which document was requested.

You're done when /docs/guides/routing shows guides/routing on the page. Try a few deeper paths in the URL bar — one page catches them all.
