/* ==========================================================================
   Sign-in page (Views/Account/Login.cshtml, docs/LOGIN.md) — the same for every
   organisation (docs/BRANDING.md). Loaded after Bootstrap and app.css (_Head), so the
   form uses Bootstrap's own controls; everything here is prefixed sign-in-.

   Wide screens: the product on a navy panel on the left, the form on the right.
   Under 900px: one column, the product above the form, compact; under 600px the
   list of what it does is left out so the form is reached without scrolling.
