The plain-English version
A browser capability that lets an application receive relative pointer movement while locking the pointer to a target.
Why it matters
It supports mouse-driven game cameras and needs a user-visible path into and out of the captured mode.
Let’s make it click
A game requests capture from its Start interaction and explains how the player can release control to reach the page.
Vibe Bro’s heads-up
Pointer lock and fullscreen are separate capabilities; do not assume obtaining one also grants the other.
