- New export_tiles.sh: merges per-area streams → combined GeoJSON → MBTiles (Z8–14) + line-delimited GeoJSON; optional Mapbox upload via Uploads API (--upload flag)
- New areas_registry.json: maps area slug → output dir + WGS84 bbox for clip-before-merge; supports --auto discovery via metadata.json
- run_pipeline.sh: write output//metadata.json after each run; re-extract lakes on every run when --osm-file provided (was cached)
- 01_grass_hydro.sh: export streams_wgs84.gpkg (WGS84) after GRASS step
- 00_setup.sh: add tippecanoe + boto3; skip brew packages already installed
- README.md: document tile export workflow, options, and folder structure
