"""ORCH-067 — Group D: the shared plane_issue_link helper (AC-12).

``plane_issue_link(work_item_id, plane_issue_id=None, project_id=None, repo=None)``
is the single source of the clickable issue number for cards AND alerts. It
returns ``<a href=...>ORCH-NNN</a>`` when a usable Plane browser URL can be built,
and ``html.escape(work_item_id)`` otherwise. It must NEVER raise — including on
None arguments and a loopback base. No DB and no network are touched by this unit
(project_id is passed explicitly here), so these are pure settings-driven cases.

Test id TC-12 from 04-test-plan.yaml.
