uf_view.h

// uf_view.h - the dashboard renderer, itself a uniflow module.
//
// FEATURE FOCUS: a renderer is just another flow on the same pump. It reads
// every runner's row with plain member access (no lock) because they share the
// thread. Its frame cadence uses a REAL-time UFTimer (default ctor), NOT the
// virtual clock - so when the user pauses the sim (clock frozen), the runners
// stop but the dashboard keeps redrawing and shows [PAUSED].
