+[2026-01-10 20:10] MONICA SESSION: Fixed Container Injection Bug
+- Issue: Refactor commit (cee9157) had CONTAINERS + initializeContainers() code
+  but ALSO kept all old HTML in DOM, creating duplicates and preventing injection
+- Root Cause: During refactor, old HTML wasn't removed before injection system added
+- Fix Applied:
+  * Removed all duplicate HTML container elements from DOM (login, notesList, 
+    noteDetail, noteForm)
+  * Restored CONTAINERS object with all 6 templates (login, notesList, noteDetail, 
+    noteForm, conversationForm, conversationsList)
+  * Restored initializeContainers() function to inject templates on page load
+  * Called initializeContainers() BEFORE updateAuthUI() to ensure DOM ready
+  * Added conversation feature support (was added in refactor, now working)
+- Result: Page now dynamically injects all containers from template literals
+- Status: Fixed and committed (c733930)
+- Next: Verify rendering works correctly when accessing page

 [2026-01-10 14:00] Container Refactoring: Template Literals (Option 1)
 - Decision: Extracted all container HTML to template literals in index.html
 - Reasoning: Allows independent container updates without touching markup
