<!--
  pisg landing page: one static file, no PHP, no cron, no libraries.

  pisg writes channels.json next to each channel page (option ChannelIndex): for every channel its
  totals, a 24-hour profile, the last 30 days and the top talkers. This page turns that into the
  statistics of the statistics: what all channels add up to, how they compare, and a link to each
  channel's own page. Copy this file into the folder your channel pages are written to, next to
  channels.json. It works on any static host, including GitHub Pages.

  Change the two lines marked EDIT below to rename the page.
