Add ocean bioregionalization / biogeographic classification

[boettiger-lab-llm-agent]

Dataset

Global ocean bioregionalization — pelagic and/or benthic biogeographic provinces (Costello et al. marine realms, GOODS bioregional classification, or Spalding et al. MEOW).

Upstream STAC import: boettiger-lab/data-workflows#68

Context

Bioregions provide ecological context for assessing representativeness of MPA candidate networks — whether proposed areas cover the full range of ocean biomes. Essential for systematic conservation planning.

STAC catalog status

Tracked in data-workflows#68. Not yet in catalog.

App integration

• STAC collection available in catalog
• PMTiles layer added to layers-input.json
• H3 hex parquet for SQL spatial joins
