/* controls.css — redesigned Settings modal (two-pane) + reusable form controls.
   Everything is token-driven so all 7 themes work; scoped under .settings-modal
   so it never disturbs the other modals that share .modal-content chrome.
   Controls keep their native <input>/<select> elements (and their ids) — these
   rules only restyle them, so the settings JS (.value/.checked/change) is
   unchanged. */
