Depending on the context, mélange can mean variety cf. ‘un mélange de styles’
A mix of styles?
Variété is a French word, meaning variety. If the interpretation used in the screenshot was the intended goal, then that word was available too.
Mélange can sometimes be interpreted as a “variety” in a figurative sense, it doesn’t directly translate to “variety” in the way variété does - there is semantic overlap.
This is why literature is dying. If it’s not literally, explicitly, no ambiguity at all stated, then it doesn’t exist. Have you never heard of what a pun is? It’s a literal play on words. Twisting them slightly for the sake of a joke.
People can’t understand this and then they jump on Reddit/Lemmy and have “discussions” where they do the same shit and can’t grasp any nuance or thought deeper than surface level.
