/**
 * Variant CSS: logos--single-row-ticker
 * Layer 2 - Path B logos role (2026-06-06).
 *
 * ONE slim row of monochrome faux-SVG wordmarks (currentColor) on a TRUE
 * continuous, seamless scroll. The track holds the set twice (the second half
 * is an aria-hidden decorative clone), so translateX from 0 to -50% lands on an
 * identical frame — the loop has no gap or jump. Both edges of the viewport
 * dissolve into the background via a horizontal mask (edge fade). When motion
 * is reduced the animation stops, the clone half is removed, and the row simply
 * centres as a static line (no mask). Logos read muted, lift to the accent on
 * hover. Structurally distinct from the two-row oscillating drift
 * (dual-row-marquee), the static fade-mask text row (marquee-fade), and the
 * static vertical-rule row (mono-row-divided).
 * Every selector scoped to .universal-logos--single-row-ticker (no leak).
