   The "Base" block below is a copy of deltavant/privacy/style.css — the
   stylesheet the (frozen, in-Play-review) privacy pages use. NEVER edit that
   file; if its palette or typography ever changes, mirror the change here.

   Layout contract: marketing pages set <body class="site"> so the 820px
   policy column width is lifted for them only.
