c:feathers

A convention tag — the shared namespace mods use so they can work with each other's items. This is the compatibility signal; a vanilla tag is not.

Written as c:feathers, forge:feathers. NeoForge renamed the convention namespace at 1.21, so one agreement between the same two mods ships under two strings; the rows are keyed on the canon form and every spelling is kept.
