RCWeb Stack Above Controller

The Stack Above Controller app (app/stack-above-control) is the phone companion for the Stack Above display. Each player joins from the QR code, keeps a private hand, and sends legal reset-loop moves back to the main screen.

What it does

• Private hand view: Shows each player's personal cards and highlights the number or reset cards that can be played now.
• Simple turn actions: The phone exposes start, draw, and sit-out controls so younger players can make a move quickly.
• 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-above sends receiveSnapshot updates containing the current public table state and this player's hand.
• Simple action calls: The phone sends back playCard, drawCard, and restRound 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.
