Transmission Line Loading and Utilization
-----------------------------------------

Two transmission views:

1. **Loading ranked** — line loading (% of rating) sorted descending,
   showing which lines hit the highest utilization across the horizon.
2. **Utilization** — distribution of hours each line operates above
   threshold percentiles (90/95/99% of rating).

The Sienna RTS-GMLC fixture is solved with ``DCPPowerModel``, so the
simulation store carries ``FlowActivePowerVariable__Line`` data and
these plots work out of the box. The same calls work against a Plexos
scenario (``PlexosScenario(simulation_files=...)``) — the transmission
API is shared across scenario types.
