feat: add zoom control with accessibility and persistence
UI Components: - Fixed bottom-center zoom slider (50%-200% range, step 5%) - Modern glass-morphism design with gradient slider track - Reset button with smooth rotation animation - Real-time zoom percentage display - Fully responsive (desktop/tablet/mobile) Functionality: - CSS transform-based zoom (GPU accelerated) - localStorage persistence across sessions - Keyboard shortcuts: Ctrl/Cmd +/-/0 - Smooth transitions with debouncing (50ms) - Scroll position preservation during zoom - Print mode: Temporarily resets to 100% Accessibility (WCAG AA): - Complete ARIA labels and live regions - Keyboard navigation support - Focus indicators on all interactive elements - Screen reader compatible (announces zoom level) - Touch-friendly (44px+ targets) Integration: - Follows existing toggle patterns (length, logos, theme) - Initializes in initPreferences() - Works with print-friendly mode - Hidden in print (.no-print class) - Bilingual support (English/Spanish) Performance: - will-change: transform for compositor layer - Debounced slider input for smooth dragging - requestAnimationFrame for scroll preservation - No layout thrashing (transform-only changes) Technical Details: - Range: 50-200 (prevents unusability, allows 2x mag) - Transform origin: top center (maintains alignment) - Transition: 300ms cubic-bezier (material design) - Storage key: 'cv-zoom' - Default: 100% (normal view)
