• Content Loading Card

  A card-shaped placeholder that breathes with a slow opacity pulse while a large image block and two lines of text are still loading.

• Activity icon

  A vital-signs trace that draws itself left to right across a flat line, spikes once, then flattens again.

• Launch orbit button

  A pill that breathes a ring outward on a loop, scatters its dust motes on hover, and sends a small craft looping across the label.
