Conversation
Effect map is the Functor instance, with the same body as the old effect-only function. Array, Maybe, and Either have instances. The 2026-10-04 annotations boards move passing resolution from 270/413 to 276/413 and L6/M7 from 124/413 to 125/413. Functor and <$> leave the first-blocker names. Refs #94
