Closes #136

@nusuke. Thanks for working on this.
This is not the structure for variants.
It's this:

const button = cva({
  base: { },
  variants: {
    visual: {
      solid: { bg: 'red.200', color: 'white' },
    },
  },
})

Instead of

const button = cva({
  base: { },
  variants: {
      solid: { bg: 'red.200', color: 'white' },
  },
})

Also, we probably want to make this work for keys in css({}) not just recipes.

@anubra266 .
Thank you for your response.

The variant structure has been fixed.

We have confirmed that the same problem occurs with css({}).
I change !isRecipeVariant() to !isInPandaFunction()
Please point out if I am using the wrong helper function.
