/* helloastreon.com: Astreon, and its first product, Folio (/folio).
   Follows the conference card and the three letters (brand/letters in the project files): Newsreader for headlines
   and IBM Plex for text, the letters' light panels, and the oxblood index tab that numbers 1 Who it's for,
   2 What it does, 3 Why Folio. Oxblood is only the tabs, the cite squares and the offer line.
   The order of things shows who's who: Astreon in the header, and Folio as a product inside the page (its masthead)
   and under Astreon in the footer. Astreon is owned by ACEBOT LLC; only Who we are and Privacy say so. */
