-name: Mirror main to knot (Tangled)
-
-# Keeps knot.aesthetic.computer:aesthetic.computer/core in sync with GitHub's main.
-# Fires on every push to main (including PR merges and bot commits). knot is the
-# production source for lith; keeping it mirrored means lith doesn't miss
-# anything landed via GitHub.
-#
-# Opposite direction (knot → GitHub) can't be automated the same way (knot is
-# a managed Tangled instance, no hooks). Relies on the user pushing locally
-# via the dual-pushurl remote to cover direct-knot cases.
