"""ORION triage target catalogue - the ground-truth dataset for fine-tuning and evaluation.

Each target is a dict with keys ``name``, ``lon``, ``lat``, ``cat`` (HIGH / MEDIUM / LOW),

and ``reason`` (human-written triage justification). The catalogue is split into three

lists by priority:

* `LOW_TARGETS`: featureless natural terrain (oceans, deserts, forests, ice).

* `MEDIUM_TARGETS`: standard human civilization (cities, suburbs, farmland).

* `HIGH_TARGETS`: extreme-scale strategic or geological anomalies.

`ALL_TARGETS` concatenates all three and is consumed by `data_gen` for

dataset generation and splitting.

See the [target morphology breakdown](../../../../guides/studies/) for the full

taxonomy of sub-categories within each priority level.
