90:1 (1s wall = 90s sim) is the finest tick resolution. Longer
horizons use coarser time steps (1min, 10min, 1hr, 6hr, 1day)
so they cover their full window in seconds, not hours/days.

Grounded ratio based on ABIDES/ECMWF benchmarks. Single global clock
shared by all horizons. Wall time for full window: hourly ~40s,
daily ~16min, weekly ~1.9hr, monthly ~8.3hr, annual ~4.2d, 5yr ~20.8d.

Hourly–weekly: full window in ≤1 wall-second (3600:1 to 604800:1).
Monthly: daily ticks, 30s wall for full window.
Annual: weekly ticks, ~52s wall.
5-year: monthly ticks, ~60s wall.

Hourly 3600:1, daily 86400:1, weekly 604800:1, monthly 2.6M:1,
annual 31.5M:1, 5-year 158M:1. Each horizon tick-advances at the
speed needed to cover its full prediction window in 1 wall-second.

All sims advance every tick continuously. The 360:1 floor means the
slowest system produces 1 simulated hour per 1 wall-clock second.
