// PanelCounter.cs
// The simplest custom panel (CreatePanel): just an ICON and a NUMBER floating on the screen, with no card or background
// behind it. Every time the object this script is on (or ClickTarget) is clicked by ANY player, the number goes up for
// EVERYONE at once, and players who join later see the current number. Place it anywhere on screen with ScreenX / ScreenY
// (a percent of the screen's width and height) and a Pivot. A good fit for a shared tally, a team score, a "people here"
// count, a collectible counter, and so on.
