/**
 * Adds the animated PayFit AI gradient treatment to an enabled interactive
 * host without requiring decorative markup.
 *
 * The host must be `uy:relative`, `uy:isolate`, and `uy:group`; its opaque
 * surface must be layered above the pseudo-elements. Set
 * `--uy-ai-gradient-effect-surface-radius` to the surface's actual corner
 * radius. This utility expands that radius for its layers so their curvature
 * stays aligned when they extend outside the surface.
 *
 * `::before` is the low-opacity, blurred glow. It extends by `spacing-100`
 * around the host and becomes visible on hover and focus-visible. `::after`
 * is the sharp gradient border: outlined controls show a resting border,
 * hover and focus-visible expand it to 2px, and pressed contracts it to 1px.
 * Both layers read `--uy-ai-gradient-angle`; the `gradient-rotate` animation
 * updates that typed custom property, so the gradient continues rotating when
 * a hover or focus-visible interaction becomes pressed.
 *
 * Apply this utility only while the host is enabled. Disabled and loading
 * controls must provide their own non-animated border and surface tokens.
 * Pair it with {@link aiGradientSurfaceEffect} on the opaque surface for the
 * 6% interior overlay.
 * @example
 * ```tsx
 * const aiAction = uyTv({
 *   base: [
 *     'uy:relative uy:isolate uy:group uy:border-2 uy:border-transparent',
 *     'uy:[--uy-ai-gradient-effect-surface-radius:var(--uy-radius-75)]',
 *   ],
 *   compoundVariants: [
 *     {
 *       isDisabled: false,
 *       className: aiGradientEffect({ variant: 'outlined' }),
 *     },
 *   ],
 * })
 *
 * const aiActionSurface = uyTv({
 *   base: [
 *     'uy:absolute uy:z-10 uy:rounded-[var(--uy-ai-gradient-effect-surface-radius)]',
 *     'uy:bg-surface-neutral',
 *   ],
 *   compoundVariants: [
 *     {
 *       isDisabled: false,
 *       className: aiGradientSurfaceEffect(),
 *     },
 *   ],
 * })
 * ```
