A clean, elegant motion graphics timeline animation on a soft dark background (deep navy or charcoal, not pure black). A thin, smooth horizontal line stretches across the frame in a warm gold or soft teal color. Exactly four small circular dots are evenly placed along the line — no more, no fewer. A soft glowing dot travels gently and smoothly along the line, moving from the first point to the second, pausing briefly, then continuing to the third, and finally the fourth. Each point gently pulses with a soft light glow only when the traveling dot reaches it, then returns to a calm steady glow. The overall mood is minimal, elegant, and documentary-style — like a premium biography or business storytelling infographic. Muted, sophisticated color palette, gentle easing motion, no harsh flashes or sparks, flat modern vector design. Calm and refined pacing throughout.
