   Morphing Circular Trigger
   Used wherever a small circular CTA appears on SSV.
   - Idle  : solid red (#FF281B), arrow at rest angle.
   - Hover : circle morphs to translucent dark, arrow
             rotates, optional underlying media reveals
             through the circle (portal).
   - Optional magnetic pull toward cursor within 100px.
