   mailstack — webmail for AS206208.

   The visual language is taken from as206208.one: near-black green-tinted
   background, a single lime accent, Geist for type, 8px/16px radii, and thin
   hairline borders. Dark only, like the site — a light theme would be a second
   design to maintain and would not match anything the brand shows elsewhere.
