fix: icon toggle real-time rendering + hyperscript architecture cleanup

CRITICAL FIX: Icon toggle now works without page refresh
- Changed class name from 'show-logos' to 'show-icons' (CSS mismatch bug)
- Updated localStorage key from 'cv-logos' to 'cv-icons'
- Fixed toggleIcons() function in cv-functions.js

HYPERSCRIPT ARCHITECTURE:
- Moved 6 toggle functions from hyperscript to JavaScript (cv-functions.js)
- Solves hyperscript 0.9.14 parser limitation (max 3 def statements total)
- Upgraded hyperscript from 0.9.12 to 0.9.14
- Fixed operator precedence in keyboard shortcuts
- Cleaned view-controls.html templates (inline → function calls)

NEW FILES:
- static/js/cv-functions.js - Global toggle functions (6 functions)
- HYPERSCRIPT-RULES.md - Permanent architecture documentation
- tests/mjs/0-zoom.test.mjs - Zoom functionality test
- tests/mjs/1-toggles.test.mjs - Comprehensive toggle test with real-time verification
- tests/TEST-SUMMARY.md - Test suite documentation

TESTS:
- Real-time DOM update verification (no refresh required)
- Screenshot capture for visual regression
- localStorage persistence validation
- Toggle synchronization between action bar and menu

BREAKING CHANGE: localStorage key changed from 'cv-logos' to 'cv-icons'
Users may need to re-toggle icons preference on first load after update.

+# Hyperscript Development Rules
+
+## MANDATORY RULES - ALWAYS FOLLOW
+
+### Rule 1: Code Cleanliness
+**More than 3 lines of hyperscript → Move to function in file**
+
+- Inline hyperscript in HTML should be kept minimal (≤3 lines)
+- Longer logic MUST be extracted to named functions in .\_hs files
+- HTML templates should be clean and readable
+
+### Rule 2: File Structure - Hyperscript 0.9.12 Limitation
+**Maximum 3 `def` statements TOTAL across ALL files**
+
+⚠️ **CRITICAL**: Hyperscript 0.9.12 has a parser limitation - more than 3 `def` statements **across ALL loaded .\_hs files** causes:
+```
+Error: Expected 'end' but found 'def'
+```
+
+**Solution for Global Reusable Functions**: Use regular JavaScript instead
+- `static/js/cv-functions.js` - Global toggle and utility functions
+  - toggleCVLength(), toggleIcons(), toggleTheme()
+  - syncPdfHover(), syncPrintHover(), highlightZoomControl()
+
+**Solution for Hyperscript-Specific Logic**: Keep max 3 defs
+- `static/hyperscript/functions._hs` - ONLY hyperscript-specific utilities (printFriendly, initScrollBehavior, handleScroll)
+
+**Why JavaScript for Global Functions:**
+- ✅ No artificial limits
+- ✅ Better performance (native JS)
+- ✅ Better debugging
+- ✅ Can still be called from hyperscript using `call toggleIcons(my.checked)`
+
+### Rule 3: HTML Structure Cleanliness
+**HTML must be as clean as possible regarding hyperscript**
+
+✅ **GOOD** - Clean, readable:
+```html
+<input type="checkbox"
+       id="lengthToggle"
+       _="on change call toggleCVLength(my.checked)">
+```
+
+❌ **BAD** - Inline logic nightmare:
+```html
+<input type="checkbox"
+       id="lengthToggle"
+       _="on change
+            if my.checked
+              remove .cv-short from .cv-paper
+              add .cv-long to .cv-paper
+              set localStorage['cv-length'] to 'long'
+              set #lengthToggleMenu's checked to true
+            else
+              remove .cv-long from .cv-paper
+              add .cv-short to .cv-paper
+              set localStorage['cv-length'] to 'short'
+              set #lengthToggleMenu's checked to false
+            end">
+```
+
+## File Organization
+
+```
+static/hyperscript/
+├── functions._hs   → Core utilities (3 defs max)
+├── toggles._hs     → Toggle functions (3 defs max)
+└── hover._hs       → Hover sync functions (3 defs max)
+```
+
+### Load Order in templates/index.html:
+```html
+<script type="text/hyperscript" src="/static/hyperscript/functions._hs"></script>
+<script type="text/hyperscript" src="/static/hyperscript/toggles._hs"></script>
+<script type="text/hyperscript" src="/static/hyperscript/hover._hs"></script>
+<script src="https://unpkg.com/hyperscript.org@0.9.12"></script>
+```
+
+## Required Functions
+
+### Core Functions (functions._hs)
+1. `printFriendly()` - Handle print-friendly view
+2. `initScrollBehavior()` - Initialize scroll variables
+3. `handleScroll()` - Manage scroll behavior and fixed button positioning
+
+### Toggle Functions (toggles._hs)
+1. `toggleCVLength(isLong)` - Switch between short/long CV
+2. `toggleIcons(showIcons)` - Show/hide icons
+3. `toggleTheme(isClean)` - Switch between default/clean theme
+
+### Hover Sync Functions (hover._hs)
+1. `syncPdfHover(show)` - Sync hover state across PDF buttons
+2. `syncPrintHover(show)` - Sync hover state across print buttons
+3. `highlightZoomControl(show)` - Highlight zoom control on hover
+
+## Why These Rules Exist
+
+### Maintainability
+- Functions with descriptive names are self-documenting
+- Easier to test and debug
+- Changes in one place instead of scattered across templates
+
+### Performance
+- Browser caches .\_hs files
+- Reduces HTML payload size
+- Cleaner separation of concerns
+
+### Hyperscript 0.9.12 Limitation
+- Parser breaks with >3 `def` in single file
+- MUST split into multiple files
+- Each file: ≤3 `def` statements
+
+## 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
+
+✅ **DO**: Split functions across multiple .\_hs files
+✅ **DO**: Keep HTML clean with function calls
+✅ **DO**: Maintain all required functions for clean architecture
+
+## Testing After Changes
+
+1. Check browser console for parse errors
+2. Verify all functions are defined (no "X is null" errors)
+3. Test all toggles work correctly
+4. Hard refresh browser (Ctrl+Shift+R) to clear cache
+

+# Test Suite Summary
+
+## Test Organization
+
+All tests are now organized in `/tests/mjs/` with numbered prefixes for execution order.
+
+### Available Tests
+
+| Test File | Purpose | Status |
+|-----------|---------|--------|
+| `0-zoom.test.mjs` | Zoom control functionality | ✅ Ready |
+| `1-toggles.test.mjs` | Comprehensive toggle testing with real-time verification | ✅ Ready |
+
+## Test Improvements
+
+### 1-toggles.test.mjs Enhancements
+
+**Key Features Added**:
+1. ✅ **Real-time visual verification** - Tests verify DOM updates happen immediately without refresh
+2. ✅ **Screenshot capture** - Takes before/after screenshots for icon toggle
+3. ✅ **localStorage validation** - Verifies state persistence
+4. ✅ **Synchronization testing** - Ensures action bar and menu toggles stay in sync
+5. ✅ **Detailed reporting** - Clear pass/fail for each test with explanations
+
+**Tests Performed**:
+- Length Toggle (Action Bar)
+- Icon Toggle (Action Bar) - **with screenshot verification**
+- Theme Toggle (Action Bar)
+- Length Toggle (Menu + Sync)
+- Icon Toggle (Menu + Sync) - **with real-time rendering check**
+- Theme Toggle (Menu + Sync)
+
+**Critical Addition**: Tests explicitly check if visual changes happen without page refresh (the bug reported by user)
+
+## Running Tests
+
+```bash
+# Individual test
+bun tests/mjs/0-zoom.test.mjs
+bun tests/mjs/1-toggles.test.mjs
+
+# All tests in order
+for test in tests/mjs/*.test.mjs; do bun "$test"; done
+```
+
+## Test Output
+
+Each test provides:
+- Clear ✅/❌ indicators
+- Before/after state comparison
+- localStorage verification
+- Console error detection
+- Summary with total pass/fail count
+
+## Screenshots
+
+Toggle test saves screenshots to `tests/screenshots/`:
+- `before-icon-toggle.png`
+- `after-icon-toggle.png`
+
+Use these to visually verify rendering happens without refresh.
+
+## Notes
+
+- Server must be running on http://localhost:1999
+- Tests run in headed mode (browser visible) for manual verification
+- Press Ctrl+C to exit after reviewing results
+- All tests are executable (`chmod +x` already applied)
+
+## Next Steps
+
+Additional tests to add:
+- Keyboard shortcuts test (L, I, V keys)
+- Hamburger menu animation test
+- Print/PDF button tests
+- Responsive design tests

+# CV Project Test Suite
+
+Organized test files for the CV application. All tests use Playwright for browser automation.
+
+## Test Files
+
+### 0-zoom.test.mjs
+**Purpose**: Test zoom control functionality
+- Verifies zoom control elements exist
+- Tests visibility toggle
+- Validates zoom slider interaction
+- Checks real-time zoom updates
+
+**Run**: `bun tests/mjs/0-zoom.test.mjs`
+
+### 1-toggles.test.mjs
+**Purpose**: Comprehensive toggle testing with real-time visual verification
+- Tests all 3 toggles (Length, Icons, Theme)
+- Validates action bar toggles
+- Tests hamburger menu toggles
+- Verifies synchronization between action bar and menu
+- Checks localStorage persistence
+- **Critical**: Validates that toggles update DOM immediately (no refresh needed)
+- Takes screenshots for visual comparison
+
+**Run**: `bun tests/mjs/1-toggles.test.mjs`
+
+## Running All Tests
+
+```bash
+# Run individual tests
+bun tests/mjs/0-zoom.test.mjs
+bun tests/mjs/1-toggles.test.mjs
+
+# Run all tests sequentially
+for test in tests/mjs/*.test.mjs; do
+  echo "Running $test..."
+  bun "$test"
+  echo ""
+done
+```
+
+## Test Requirements
+
+- Server must be running on http://localhost:1999
+- Browser window will stay open after tests for manual verification
+- Press Ctrl+C to exit test
+
+## Test Output
+
+All tests provide:
+- ✅ Clear pass/fail indicators
+- 📊 Summary of results
+- ❌ Detailed error messages
+- 🎉 Success confirmation
+
+## Screenshots
+
+Toggle tests save screenshots to `tests/screenshots/`:
+- `before-icon-toggle.png` - Before clicking icon toggle
+- `after-icon-toggle.png` - After clicking icon toggle
+
+Use these to visually verify rendering changes.
