Zoom level persistence was broken because hyperscript was setting the
container's value instead of the slider's value on page load.
Changes:
- Fix zoom-control.html line 10: set #zoom-slider's value (not 'my value')
- Add comprehensive zoom persistence test (10-zoom-persistence.test.mjs)
- Update cv-functions.js documentation to clarify hyperscript interop
- Add zoom control feature to README
Test results: 5/5 tests pass
- Zoom saves to localStorage when changed ✅
- Zoom restores correctly on page reload ✅
- Reset to 100% works and persists ✅
Architecture note:
- Hyperscript 'call' within _="" attributes requires global JS scope
- JavaScript wrappers bridge window exposure to hyperscript evaluate()
- Pattern: window.fn() → _hyperscript.evaluate('hyperscriptFn()')
