// PanelScoreboard.cs
// A custom UI panel (CreatePanel) shown as a screen OVERLAY in a corner behind the platform's own UI. It is NOT shown
// to everyone automatically: a player gets it when they click a button object you slot in, or the object this script is on (and can close it with the x,
// then click again to reopen). It shows a shared round score every player sees the same, a coin count that is each
// player's own, and a
// "Collect a coin" button. A click comes back to this server script as that player (e.panel event): their own coins go
// up for them only, the shared total goes up for everyone, and both update live on every screen.
//
// This is the difference from a HUD: a HUD is the player's personal window; a panel is the world's own UI surface. Set
// it to SetMode(PanelMode.WorldSpace) instead and the very same panel stands in the world for VR (see PanelWorldMenu).
