/* DESIGN RULES (apply to every tool page): consistent 1px borders, no box shadows,
   no hover transforms, NO light-gray fills — surfaces are white with borders; hover
   feedback = border/text color change, never a gray wash. Modals must use
   .tui-modal-overlay (z-index above the reseller bar — never page-local modals). */
