/**
 * LiveTemplate CSS Custom Property Defaults
 *
 * These custom properties configure lvt-fx:* directives.
 * Override them in your own stylesheets to customize behavior.
 *
 * Duration values should include the "ms" unit so the variable remains
 * a valid CSS time value and can be used directly in animation/transition
 * properties. The directives parse these with parseInt which strips the
 * unit, so both forms work, but "500ms" is the recommended form.
 *
 * Usage:
 *   [lvt-fx\:scroll]    { --lvt-scroll-behavior: smooth; }
 *   [lvt-fx\:highlight] { --lvt-highlight-color: yellow; --lvt-highlight-duration: 1000ms; }
 *   [lvt-fx\:animate]   { --lvt-animate-duration: 500ms; }
