   The week's bookmarks on the talks.avi.nyc stage: a black room, burgundy,
   cyan and amber lights, Playfair Display beside DM Sans. Each topic in a
   week wears one light, the way each talk wears its own costume. The archive
   borrows avi.nyc's ruled writing list. Light mode is avi.nyc's Coastal Sprint.
