(** Serving the static assets embedded at build time.

    Assets are compiled into the executable by [ocaml-crunch] (see the rule in
    [lib/dune]), so a deployment is a single binary with no asset directory to
    keep in sync. Responses are cached for a day; because the content ships with
    the binary, a new release is the only thing that can change them. *)

val handler : Dream.handler
(** Dream handler for requests under [/static/**]. Looks up the path in the
    embedded asset store and responds with appropriate content type and cache
    headers, or 404 when the asset is not found. *)
