/* The front door: log in, sign up, confirm email.

   A split. The form on paper at the left; at the right, a 440px accent field
   with the product's flow — Quotation, Invoice, Receipt — stacked down it. The
   accent field is allowed here and nowhere else in the app: this screen is
   seen once a session and can afford to be loud. The dashboard can't.

   On a phone the field becomes a 210px band across the top with the flow on
   one line, and the primary pill sits at the foot of the screen rather than
   under the fields, where a thumb already is.

   Shared by login.html, signup.html and verify.html so the three can't drift. */
