/* website/style.css
   The HomeStock company site. Deliberately ONE small stylesheet, no framework, no build step:
   this deploys as plain static files so it can never break the way a toolchain can, and so
   anyone can read it a year from now.

   It is NOT the app. The app lives at its own address and keeps its own design system; this
   is the site people land on before they have an account. Shared vocabulary (the accent, the
   type scale, the 44px targets) but no shared code — coupling a marketing page to App.js is
   how a marketing page starts breaking on a refactor. */
