15 * PR preview lifecycle, mirroring the CI workflow in the Cloudflare
16 * tutorial (part 5): a pull request deploys `--stage pr-N` and tests it,
17 * the stack posts the preview URL as a PR comment, and merging runs the
18 * `prod` deploy and the preview cleanup in parallel.
19 *
20 * Left: the pull request, whose checks box expands to show the tests while
21 * they run. Right: GitHub Actions, which expands the active step's log the
22 * way GitHub does.
23 *
24 * Every frame is derived from (step, ms elapsed in that step), so any step
25 * can be jumped to directly from the tab bar.
