/* Sohm Login Page Styles
   Light look of ra-kanzlei.at (Rechtsanwälte Palkovits & Sohm): white surfaces, text #222222,
   logo anthracite #3e3d40, website red #bc0d20 (buttons, top bar) with the logo red #e2001a and the
   dark reds #8c0a18 / #650a14 for hover and links, cool light greys #f8f9fa / #eff1f3 / #dee2e6 like
   the website surfaces. No external fonts (the website self-hosts Roboto; it is only named here and
   used when installed locally).
   Logo: /css/sohm/logo_full.png (anthracite wordmark with red ampersand and the "Rechtsanwälte"
   line, transparent, 369 x 76 px) replaces the app's login logo via content: url() and sits on a
   white band with a red top edge like the website's red top bar. All colours are fixed so the page
   looks the same whatever theme is selected. */
