/**
 * Logo Marquee styles.
 *
 * Naming convention: BEM-ish, all prefixed with `itm-logo-marquee` to avoid
 * collisions with Elementor, themes and other plugins.
 *
 * The animation distance is driven by the `--itm-lm-distance` custom property,
 * which JavaScript sets to the width of exactly one original sequence. The
 * track is translated by that distance and then the animation restarts, which
 * is seamless because the clones that follow are identical to the originals.
