/* Sim2Bot landing page.
   Deliberately plain CSS with no build step: this is a static site served from
   its own Cloudflare Pages project, and a toolchain would be more to maintain
   than the page is worth. Tokens mirror src/styles/global.css so the marketing
   page and the app look like the same product. */
