RCWeb Stack Snap Controller
The Stack Snap Controller app (app/stack-snap-control) is the phone companion for the Stack Snap display. Each player joins from the QR code, keeps a private hand, and sends legal card actions back to the main screen.

What it does
- Private hand view: Shows each player's personal cards, highlights playable options, and keeps the draw/keep flow clear.
- Wild color choice: Wild and wild draw four cards expose a large color picker before the move is sent.
- Fast resync: The controller stores only a player id and name locally; the display pushes fresh snapshots whenever the room state changes.
How it works
- Display-driven snapshots:
stack-snap sends receiveSnapshot updates containing the current public table state and this player's hand.
- Simple action calls: The phone sends back
playCard, drawCard, and keepDrawnCard requests using rc.sendFunctionCall.
- Programmatic SVG hand: The phone renders the same generated card faces as the display so both apps stay visually aligned without static card image files.
