+PALIMPSEST PHILOSOPHICAL OVERLAY (NON-BINDING)
+================================================================================
+
+This project encourages (but does not legally require) adherence to the
+principles of the Palimpsest License - a framework for consent-based digital
+interaction and the future web.
+
+Core Principles (Encouraged):
+  - Respect for emotional and creative lineage
+  - Transparent AI training practices with explicit consent
+  - Preservation of metadata and attribution
+  - Protection of narrative intent and cultural context
+
+The Palimpsest principles represent our vision for a consent-based internet.
+While not legally binding for use of this software, we encourage all users
+and contributors to familiarize themselves with these principles.
