An electric turbulence border — the card's perimeter is a living arc: an SVG rounded-rect stroke deformed by animated procedural turbulence so it writhes, crackles on seeded reseeds, and periodically misfires and re-strikes, under a soft violet corona. Hover ramps the displacement. Throttled rAF that pauses offscreen; static softly-glowing border under reduced motion.
