Serve the showcase's own stylesheet without the application's build

Plan step 38 (first batch): a route bundles all.css, showcase.css and
the application's generated scheme (Stylesheets::bundle(), found next
to its configured JSON by swapping the extension, or a Scheme::load()
fallback in tokens/scheme.css's own shape) into one long-cached,
content-hashed CSS response; a stale hash redirects to the current
one. A second route serves the fonts and SVGs its relative url()s
point at, from the package's fonts/ and svg/ folders only, MIME-typed
by extension and 404ing on ".." or an unlisted extension. Both stay
unregistered with the showcase off.
