tilt-3d

A card that tilts in 3D toward the pointer. Part of motion-anything; obeys MOTION-SPEC.md. Technique popularized by vanilla-tilt.js, reimplemented dependency-free.

When to use it

• A hero product card, cover image, or a few portfolio thumbnails where depth adds delight.

When NOT to use it (restraint)

• Dense grids — many tilting cards feel chaotic and can induce motion sickness. A few hero cards.
• Text-heavy cards (tilt hurts readability); touch-only contexts (it stays flat automatically).
