/* Hero, desk builder chat and the layout around "Your EZPZ desk" (Agent E). Tokens and
   shared classes come from landing.css; everything here is lp-hero-*, lp-build-*
   or lp-ob-*. Layout dimensions (avatar sizes, the thread's height floor and cap,
   1px borders) are the only literal sizes. Nothing moves by itself for more than
   a few seconds.
   The hero (_hero.html) is the headline and the live desk; the builder section
   (_builder.html, #build) right under it holds the chat and the desk preview.
   The desk preview is the shared personalize component (personalize/desk.css);
   only the grid around it is here. */
