/* "Studio" shell — shared design tokens + chrome for every v2-styled page.
   Ported from the client's Next.js operations-v2 prototype (globals.css +
   studio-shell.tsx). Any future v2 page extends templates/base-v2.html and
   gets these tokens/shell for free; add page-specific CSS in its own file. */
