A Prism theme descended from Monokai's palette — the name enters as itself, a dress code wears.
A modern coinage, not an inherited word: a blend that keeps the tail of Monokai (Wimer Hazenberg's widely used syntax-highlighting theme, itself a coinage of unclear derivation) while replacing its front with x-.
A theme for Prism that carries Monokai's palette forward under a name announcing the descent rather than hiding it. The name enters the corpus exactly as coined, the way a dress code wears a name rather than an argument.
