Add marine conservation priority areas (IMMAs, ISRAs, KBAs, IBAs)

[boettiger-lab-llm-agent]

Dataset

Multiple marine conservation priority area classifications:

• IMMAs (Important Marine Mammal Areas)
• ISRAs (Important Shark and Ray Areas)
• KBAs (Key Biodiversity Areas, marine subset)
• IBAs (Important Bird Areas, marine/coastal)

Upstream STAC import: boettiger-lab/data-workflows#65

Context

Priority area designations from different taxonomic communities help evaluate how well MPA candidate networks cover high-value habitat for different species groups. Useful for representativeness analysis.

STAC catalog status

Tracked in data-workflows#65. Not yet in catalog.

App integration

• STAC collections available in catalog (may be one per classification or combined)
• PMTiles layers added to layers-input.json
• H3 hex parquet for SQL spatial joins
• System prompt updated with definitions distinguishing IMMA/ISRA/KBA/IBA
