Use case: stylized-concept. Asset type: one new transparent railgun projectile sprite for a Raptor-style military science-fiction vertical shooter. A single extremely narrow vertical ballistic rail slug traveling exactly UP: sharp pale steel pointed nose, short bright ivory core, a restrained slim cyan sheath, and a tapered blue-gray wake downward. It is a solid compact dart with a visible bright tip and a modest bounded trail, not a screen-length beam, not lightning, not an explosion. Top-down orthographic overhead view, perfectly straight and centered. Subject width:height about1:5; logical canvas4x20 pixels and16x80HD. Chunky crisp small-game silhouette with refined original metal/light detail forHD. One complete object on a genuinely transparent square canvas, generous blank side areas, at least15percent top/bottom transparent margin. No gun, spacecraft, text, border, background, shadow, smoke cloud, detached sparkles, branching, multiple objects or outside glow. Match restrained pale steel/ivory/cyan highlights of a classic1990s military shooter.
