# Extracted from ci.yml so workflow-level concurrency can protect this job
# from run-level cancellation (issue #458).
#
# Problem: the job-level `concurrency.cancel-in-progress: false` in ci.yml
# prevented *sibling* E2E jobs from killing each other, but GitHub still
# cancelled the parent *workflow run* when a new push arrived. Since the job
# lived inside that run, it got cancelled too.
#
# Fix: a dedicated workflow gets its own concurrency group at the workflow
# level. New pushes to the same branch queue here instead of cancelling.
# Fast jobs (platform-build, canvas-build, etc.) stay in ci.yml and continue
# to benefit from run-level cancellation for quick feedback.

# Workflow-level concurrency: new runs queue rather than cancel.
# `cancel-in-progress: false` is load-bearing — without it GitHub would still
# cancel this run when the next push arrives, defeating the whole fix.
# The group key includes github.ref so PRs don't compete with main.
