Fluxer appends an extension inferred from the resolved content type when that segment has no dot, then normalises the result so whitespace becomes `_` and every character outside letters, digits, combining marks, `_`, `.`, and `-` is dropped. A URL path with no last segment yields `media.{extension}`. Where the segment normalises to nothing, or to only dots and underscores, the filename is `unnamed`. The extension is `bin` when the content type maps to none.
