## Why this bbox

It contains the demo block from Highland Avenue to Orange Drive plus the whole north side within 50 m, with enough margin to include the streets' intersection nodes and the alley network behind the south frontage. It deliberately excludes the rest of the boulevard: larger extracts cost processing time and dilute the ODbL review.

## Coverage limits

- Building interiors, heights above the tagged value, and pavement widths are not in this data. Treat all of it as layout.
- The `height` tag exists on some buildings and is absent on others (`6838` has only `building:levels`, `6922` has neither). A missing tag is not a zero height.
- The extract has no elevation. The DEM decision is still open; see `ROADMAP.md`.

## Attribution obligation

Any distributed derived output keeps "© OpenStreetMap contributors" and the licence link. The `0.1.0` release check requires the attribution to be visible in the shipped build.
