/* ToolKnit reusable native <dialog> skin.
   Load this stylesheet only on pages that need it. Use .tk-dialog on <dialog>,
   .tk-dialog__body + .tk-dialog__footer inside, and .tk-dialog__button for actions.
   Keep dialog IDs, content, showModal(), consent and close handlers in the caller.
   Native modal focus trapping/Escape remain intact. No global element selectors. */
