+-- | Serve files from a StaticAssets directory using the obelisk-style

+-- the hashed asset, serves it with proper caching + encoding negotiation).
+--
+-- Previously used @Snap.serveDirectory@, which does trailing-slash
+-- canonicalization for the asset directories (each hashed asset is
+-- structured as a dir with @type@/@target@/@encodings@ files), so every
+-- request for @/ghcjs\/all.js@ got 302'd to @/ghcjs\/all.js\/@ and fell
+-- through to the SPA HTML. Matches obelisk-v1's @serveStaticAssets@.
