"""
Glass by Unrivaled - rebrand overlay for Postiz (upstream v1.47.0, AGPL-3.0).

Applies user-facing branding only. Does NOT rename code symbols, imports,
package names, or env keys. Upstream copyright and LICENSE are untouched.

Every anchor is required: if an upstream bump moves a string, this script
exits non-zero and the image build FAILS rather than producing a silently
half-branded Glass. That is the point - re-applying is mechanical, and
drift is loud.
