/* ==========================================================================
   WC Tip & Donation — Widget Styles
   Works for both classic (shortcode) and block cart/checkout contexts.

   All colors use CSS variables so they can be overridden by the settings page
   (see WC_Tip_Shortcode::inline_styles). Fonts inherit from the site's
   primary font via `font-family: inherit`.
