// ============================================
// Animation Keyframes & Utility Classes
// ============================================
// Shared animation library for all MetaBuilder frontends.
// Uses CSS custom properties (M3 tokens) instead of SCSS variables
// so this file has no project-specific dependencies.

// ============================================
// Timing defaults (CSS custom properties)
// ============================================
// These can be overridden per-project by redefining the custom properties.
