-### Hyperscript 0.9.12 Limitation
-- Parser breaks with >3 `def` in single file
-- MUST split into multiple files
-- Each file: ≤3 `def` statements
+### Historical Note: Hyperscript Def Limit
+- **Hyperscript 0.9.12** had a 3-def limit per file (FIXED in 0.9.14+)
+- **Hyperscript 0.9.14+** has NO def limit - tested with 5+ defs
+- Multi-file organization is still recommended for maintainability, not required
 
 ## Common Mistakes to Avoid
 
-❌ **DON'T**: Put all functions in one file if you have >3 defs
-❌ **DON'T**: Write long inline hyperscript in HTML
-❌ **DON'T**: Delete functions to work around the 3-def limit
+❌ **DON'T**: Write long inline hyperscript in HTML (maintainability issue)
+❌ **DON'T**: Try to externalize event handlers that inspect `event.key` or `event.target`
+❌ **DON'T**: Forget to test after refactoring (syntax errors look like bugs)
 
-✅ **DO**: Split functions across multiple .\_hs files
+✅ **DO**: Split functions across multiple .\_hs files for organization
 ✅ **DO**: Keep HTML clean with function calls
-✅ **DO**: Maintain all required functions for clean architecture
+✅ **DO**: Test all keyboard shortcuts after any hyperscript changes

 ## Recent Changes
 
+### 2025-11-30: Major Inline Hyperscript Refactoring
+- ✅ **REFACTORED**: Body tag keyboard handlers → `keyboard._hs` helper functions
+- ✅ **REFACTORED**: Zoom control handlers → `zoom._hs` helper functions
+- ✅ **REFACTORED**: PDF modal card selection (3 identical blocks) → `pdf-modal._hs`
+- ✅ **ADDED**: `zoom._hs` - Zoom control helpers (handleZoomInput, handleZoomReset, initZoomControl)
+- ✅ **ADDED**: `pdf-modal._hs` - PDF modal helpers (selectPdfCard, handlePdfCardKey)
+- ✅ **TESTED**: All functionality verified with comprehensive tests
+
+### 2025-11-30: Multi-File Loading Bug Investigation
+- ✅ **CONFIRMED**: Multiple `<script type="text/hyperscript" src="...">` tags work correctly
+- ✅ **VERIFIED**: No multi-file loading bug in hyperscript 0.9.14
+- ✅ **TESTED**: All 6 external files + inline hyperscript work together seamlessly
+- ✅ **ADDED**: Test `tests/mjs/32-hyperscript-multi-src.test.mjs` for verification
+- 🔍 **FINDING**: Previous refactoring failures were syntax errors, NOT hyperscript bugs
+
 ### 2025-11-20: Event Handler Externalization Guidelines
 - ✅ Added Rule 4: Clear guidelines on what can/cannot be externalized
 - ✅ Navigation handlers successfully externalized (9 links → 1 function)
