 * Sponsor Tab — front-end styles.

 * Colours arrive as custom properties from the active campaign; the values here
 * are only fallbacks.
 *
 * The geometry below reproduces the Elementor tab it replaces. Before release,
 * sample the live button and confirm these six values against production:
 * background/text colours, hover colours, --sponsor-tab-top, the font stack and
 * size, the padding/border-radius, and the label's rotation direction.
