/* Defensive fix for the deferred "Your Plan — Manage" treatment
 * (v0.19.x polish item 2). Theme rules can clobber the inline CSS:
 *   - background can flip to brand-orange (matching --ww-color-b)
 *   - text color can flip to white on hover
 * Lock background, color, AND border with high specificity (3 classes
 * chained) plus !important so this stays a readable ghost button:
 * white bg + brand-color text + brand-color border, light-gray on hover. */
