   /tools - unified Tools index page
   One surface that lists every tool the logged-in user has access to,
   so they don't have to discover via the Tools dropdown alone. Mirrors
   the iOS Tools tab grid but uses the web's typography + colour
   palette (cream / teal) rather than iOS card-stack chrome.
