/* Biphase platform styles: the website's global.css carried over unchanged, plus
   only what a form needs (fields, buttons, an error line, a progress line) at
   the end. The three decisions below still hold at the careers and hr doors;
   the admin door may be denser, in its own stylesheet.

   Biphase Precision Systems — site styles.

   The whole design is three decisions, and nothing may step outside them:

   1. Colour  One background, one text colour. No greys, no lines.
   2. Type    One typeface. Text is 13px; the menu, people's names and roles, and the footer
              are 11px; photo captions are 9px semibold; the company
              details on the landing page are 8px. The logo is the only large
              thing on a page. Headings are text size in Archivo's expanded
              width; a person's name is the same lettering one size down.
   3. Space   Every distance is a step on one 8px scale, and each step has
              one job (see "Space" below).

   There is one layout for every screen: a single narrow column, centred,
   with everything aligned to its left edge. A wide screen shows the same
   page as a phone, with empty background either side. */
