Struct FPSCounter 

pub struct FPSCounter { /* private fields */ }

Tracks real render-loop frame rate using a simple per-second counter.

Updates once per second with EMA smoothing (0.9 * prev + 0.1 * current) to dampen visual jitter. The value is exposed via fps() and rendered right-aligned in the header bar.
