  // list-item-container-color
  // This does not match the spec, which defines this to be `md.sys.color.surface`.
  // However, this interferes with the use case of placing a list on other components. For example,
  // the bottom sheets container color is `md.sys.color.surface-container-low`. Instead, allow the
  // list to just display the colors for its background.

  // list-item-leading-icon-size
  // Match spec, which has list-item-leading-icon-size of 24px.
  // Current version of tokens (0_161) has 18px.
