   Demo bank website - theme
   SmartData Technologies Limited

   No bank-specific value belongs in this file. Brand colours arrive from
   theme/brand.css, which build.py writes from banks/<pack>/brand.yaml.

   Fonts load from Google but every stack falls back to a system face, because
   a demo in a bank's meeting room often has no internet.

     `only light` tells the browser to leave this page alone. Without it,
     Chrome's force-dark inverts a bank's public website into a set of greys
     nobody at that bank has ever approved - and the one thing this site has to
     be is recognisably theirs.
     The contact centre and the admin console are the opposite case: they are
