+### [2026-04-11 11:21] v1.2.2: UI Readability & Density Optimization
+**Purpose:** System-wide removal of `uppercase` transformations and `tracking-widest` spacing.

 ### 2026-04-10 (v1.2.0)
 - Implemented **Structured Categories** (Group-based) and **Item Types**.
 - Finalized **Local Authentication** with PBKDF2 (Mac/Python 3.14 compatible).

+# AI Session State - HANDOVER
+
+**Status**: UI Readability Refactor Completed (v1.2.2). Ready for Phase 6.
+**Current AI Agent**: Gemini (Antigravity)
+**Context**:
+- **UI Readability**: System-wide removal of `uppercase` and `tracking-*`. Font sizes increased from 9px/10px to xs/sm. Title Case applied to major buttons.
+- **Rules Compliance**: All changes logged in `ARCHIVE_LOGS.md` and `VERSION.json`.
+- **Git**: Working on branch `dev`. Path persisted in `.git_path`.
+
+**Next Steps**:
+1.  **Proceed to Phase 6: Audit Log Dashboard UI**. The backend already has `Log` models, but the frontend needs a more comprehensive view beyond the current "Audit History" modal if requested, OR finalize the existing ones.
+2.  Enable LDAP and test with real server (from v1.2.1 goals).
+3.  Deploy v1.2.2 to stable branch if user confirms.
