/* ==========================================================================
   Identity portal on Bootstrap 5.3 with its own design tokens on top.
   Bootstrap supplies the components (card, form-control, form-select, form-check, input-group, btn, alert,
   list-group, badge, visually-hidden); this file only sets tokens, restyles them to the tokens and adds the layouts.
   The organisation theme (accent, logo background, identity portal background settings) arrives in a separate
   stylesheet served from the portal itself (/home/IdentityTheme), so no inline style is ever needed.
   Every colour below can be changed per organisation (Cp3IdentityPortalColourCatalogue): card, text and page colours
   apply to the light scheme; brand and message colours apply in both.
   Server-rendered attributes on <html> (Views/Shared/_LoginLayout.cshtml):
     data-layout = classic | split | spotlight                     (theme setting, default classic)
     data-side   = start | end                                       (split: which side the form is on)
     data-bg     = particles | solid | gradient | image              (background mode setting)
     data-bg-fit = cover | contain | stretch | centre | tile         (image display mode setting)
     data-theme  = light | dark | device (device, or no attribute, follows the device setting)
