render_plugin_template's first three arguments are positional-only, so the service page's own `name` reaches the template. The overview names a service rather than its replica containers, and a stack chip keeps the search it was clicked under. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

"""Integration: a swarm service's own page (#5302) and the Docker overview's

|
service table (#5299, #5300) against real Postgres. The page reads the logs

and samples of every task the service ran, the live one and one Docker has

already removed (known only by its events), and a failure's "Logs →" picks

that task. Requires STEWARD_DATABASE_URL."""
