Prefix Label
The Prefix Label card adds an optional short text that appears in front of the value — typically a currency symbol, a unit or a signed indicator.

Positioning
The prefix is anchored to the left of the value and follows the value's position. When the value is dragged or repositioned through the Layout card, the prefix follows.
The End Spacing property controls how much horizontal room is left between the end of the prefix and the first character of the value. Increase it for an airier look, decrease to 0 for a tight composition.
Independent font
The prefix uses its own FontControl, independent from the value. This lets you combine, for example, a small $ prefix with a large bold value, or a light italic ≈ with a regular value.
