/* Design Studio. The layout combines the best parts of the top-ranked dashboards:
   a quiet collapsible sidebar with one primary action (shadcn, Linear), a top bar with the brand
   switcher and jump-anywhere search (Shopify Polaris), page headers with actions on the right,
   stat tiles and asset cards (Tabler, Shopify Files), and a full-width product editor (Canva, Printful).
   One UI font, a restrained palette, and brand color only where it says which brand a thing is. */
