/* ============================================================
   Nepal Land Tools
   ------------------------------------------------------------
   Layered on top of styles.css rather than replacing it, so the
   land tools are visibly part of the same site — same header,
   same cards, same type scale.

   The one place this departs from the rest of the site is the map
   screen. Everywhere else a tool is a form with a result under it;
   on the map the map IS the tool, so it takes the full viewport
   and the results dock beside it (or beneath it, on a phone).
