Border Animations & Controls

script.js wires animation speed, border width, and primary/secondary color pickers to all .demo-box elements. CSS variables (--primary-color, --secondary-color) drive pseudo-elements; dynamic @keyframes injected for glow, neon, particle, pulse. Preset color swatches and keyboard shortcuts (R reset, Space pause, C randomize).

Controls: animation speed (0.5–5s), border width (1–10px), colors
updateColors() sets CSS vars and updates rotating/glowing/morphing borders
Keyboard: R reset, Space pause/resume, C randomize colors
Filter: search animations by name; cards toggle .hidden

Theme & Accessibility

css/variables.css: light (--bg-body gradient, white cards) and dark (data-theme="dark") themes. js/theme.js toggles theme and persists in localStorage.

theme.js: border-animations-theme in localStorage
Reduce motion: 0.01ms animations when enabled; persisted
Skip link, :focus-visible, aria labels on buttons
