HackerHotel 2019 Badge note

missing rights-cleared image · local project policy · needs licensed original replacement

No HackerHotel 2019 badge image is published because the current Badge.Team source trail has not been paired with a reusable original badge photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.

The record remains source-backed and image-free rather than copying Badge.Team page media, documentation screenshots, event photos, placeholders, or generated approximations.
