-# HIPAA-aware wrapper of the existing app. This keeps the analysis and assessment
-# capabilities intact while adding PHI safeguards:
-# - PHI_MODE flags with opt-in persistence
-# - Redaction before sending content to any external LLM
-# - Safer logging (no raw PHI)
-# - Optional banner and history controls
+# app_phi_sleek.py
 #
-# NOTE: This file is designed to be a drop-in alternative to app.py.
-#       It preserves existing analysis logic and UI while adding HIPAA toggles.
+# Sleek UI + Voice-to-Text for the HIPAA-aware app.
+# IMPORTANT: All analysis/assessment logic is preserved exactly.
+# Changes are limited to the UI layout, CSS, and a client-side STT helper.
