/*
  The !important tags are added to ensure these specific button styles
  override any general styles from .tool-button, .primary-action, or .secondary-action.
  Ideally, CSS specificity would handle this, but !important provides a stronger guarantee
  if there are conflicting specificities that are hard to resolve otherwise.
  We aim to remove .primary-action and .secondary-action from these buttons in HTML.
