   Both pages rendered dark on a site whose homepage is light, and the
   login page carried a "Why Hubionis?" panel of four cards written for
   the old conference product — "Network: connect with organizers,
   speakers, and attendees". Somebody on the login page has already
   decided; they need the form, not a pitch.

   So these are built out of the homepage's own parts: the hero's
   gradient ground, the search card's hairline-and-shadow treatment, its
   flat fields divided by hairlines, and its filled action button. Same
   tokens, same radius, same weights — the login page should look like
   the place you just came from, not like a different product.
