  #
  # Why floating, not pinned: `mailglass_inbound` tracks its own version line and
  # is NOT part of the release-please linked-versions group. The v2.0 milestone
  # advanced inbound to its own 2.0.0 (breaking schema-isolation contract), so the
  # floating constraint is `~> 2.0` — it must resolve against the inbound MAJOR
  # that ships alongside this admin release. A `==` pin (the shape release-please's
  # sed step writes for the linked siblings) could write an unsatisfiable
  # cross-line version, so this dep is deliberately ABSENT from the release-please
  # PINS array in `.github/workflows/release-please.yml`. Bump the floating line by
  # hand when inbound's major advances past core's (0.2 -> 1.x -> 2.0).
  #
  # The admin reads inbound rows exclusively through the
