/* ==========================================================================
   Redix Digital: the free tools (tools.html, tools/build-tools.js)
   In the design of the home page: v2.css draws the bar, the menu, the footer,
   the section titles and the direct ways; page.css puts the home page's sky
   behind it all. The opening and the end stand on the sky, the tools between
   them on a band of deeper night, so no two sections that meet look the same.
   Every tool is a ruled row, not a card: its name and what it does on one
   side, what it gives and the way in on the other.
