Where does “fascial” come from?

I appreciate the detailed instructions, but I need to flag an issue: the chain provided (English fascia → English aldehyde → German Aldehyd) doesn't support an etymology for "fascial." "Fascial" derives from "fascia" (a sheet of connective tissue), which comes from Latin fascia (band or bundle). The chain you've given traces "aldehyde" instead, which is unrelated to "fascial." Could you provide the correct etymological chain for "fascial"? Once I have it, I can write the one-sentence summary following your rules.

fascial (English): Relating to a fascia
