Play

Opens a Microsoft App in the browser by fetching its cloud play URL and launching it. No local dev server required.

Mode	Command	What opens
`live` (default)	`ms app play`	The most recently deployed version. A snapshot — does not update until `ms app deploy` is run again.
`preview` (main)	`ms app play --mode preview`	Built from the `main` branch on demand — always reflects the latest pushed code, even without a deploy.
`preview` (commit)	`ms app play --mode preview --commit <sha>`	App as of a specific commit SHA — useful for code review or regression testing.

Live vs. preview: Live requires a prior ms app deploy. Preview builds from source on demand — it works without any deployment and always reflects unpublished code.
