Struct UpgradeTreeState 

pub struct UpgradeTreeState {
    pub bought: HashSet<TreeCoord>,
    pub cursor: TreeCoord,
    pub last_bought: Option<TreeCoord>,
}

Player-owned tree state. Small on disk: a set of i64-sized coords, a cursor coord, and the lot of the most recently bought node.

Fields

bought: HashSet<TreeCoord>

Lot coordinates of every bought node.

cursor: TreeCoord

Cursor (focus) position on the canvas, in lot coordinates. The renderer pans the viewport so the cursor’s lot sits near the center. Saved so reopening the tree lands where the player left it.

last_bought: Option<TreeCoord>

Lot of the most recently bought node. Drives the [1] last bought shortcut. None on fresh game / after prestige / after the only bought node was refunded.
