/* ============================================================
   SUSTENZA — SIGN IN / CREATE ACCOUNT
   ============================================================
   A full surface rather than a dropdown. Signing in is a task,
   not a menu: it deserves the whole window, one column, nothing
   competing with the two fields that matter.

   The measure is deliberately narrow (~340px of field). A login
   form is the one place where a wide input reads as harder, not
   easier - the eye has to travel for no reason, and every well
   made sign-in page on the web is about this width.

   Colours come from the marketing page's own tokens, so this
   surface belongs to the site rather than looking bolted on.
