   12Tile — Marketing site (landing + download pages)
   ------------------------------------------------------------
   Shares design tokens (colors/fonts) with the dashboard's
   css/style.css so the two feel like one product, but this
   stylesheet is its own file because the marketing pages scroll
   (dashboard is a fixed-height app shell) and use a different
   layout (hero, feature cards) instead of sidebar+content.
   Fonts are loaded from ../dashboard/fonts/ — same files, no
   duplication. See ../dashboard/fonts/README.md to swap them.
