The Content-Security-Policy meant for stored SVGs never applied: in
Caddy a `*` in the middle of a path does not cross a `/`, so
`path /storage/*.svg` only matched files directly under /storage, and
every upload lives in a directory below it. Two matchers, which Caddy
ANDs, cover any depth.
RemoteImage fetched with Guzzle's anonymous default User-Agent, which
Wikimedia answers with 403. It now sends `<app>/1.0 (+<app url>; media
fetcher)`, the identification such hosts ask of automated clients.
