   Light palette ①「晨雾蓝」: cobalt primary, navy dark surfaces (flaps, tags, footer), a touch of warm gold.
   Legacy class names from v1 (.key*, .panel, .ph/.pb/.pf, .sh, .pending, .closed, .led …) are kept and re-skinned so
   pages that have not been re-skinned yet still render. New code: .btn*, .card, .eyebrow, .badge (see board.css too). */
