headroom
This term describes a buffer or a margin of safety. In physical spaces, it refers to the literal gap above a person, often used when discussing vehicle interiors or architectural constraints.
In technical or financial contexts, it shifts to a metaphorical gap, representing the distance between current usage and a maximum threshold. Because it describes a quantity of space or capacity, it is treated as an uncountable noun. You would not refer to "three headrooms" in a car; instead, you would describe the headroom as being "limited," "ample," or "insufficient."
