 * InputOTP — quebi design system
 *
 * One-time-password / verification-code input built on the `input-otp`
 * package. Slots use the quebi input style (translucent field, cyan-tinted
 * border); the active slot lifts its border to brand teal with the quebi
 * teal ring. Invalid uses red; disabled dims the whole control.
