/*
 * HTS login theme — aligned to the Project Portal design system.
 * Tokens extracted from the portal's CSS bundle (projects.hts.pro):
 *   brand navy   #0d2152 / #1e3a6e      accent cyan  #00b8eb / #0096c7
 *   font         Inter (+ system stack)  light surface #ffffff, border #e5e7eb
 *   elevation    0 16px 48px #0b12202e   easing       cubic-bezier(.16,1,.3,1)
 * Injected into the paperless login page by 03-login-theme.sh.
 *
 * Structural note: paperless renders the SSO provider button AFTER </form>,
 * so the card chrome lives on the centering wrapper (form + ul together)
 * instead of on form.form-accounts.
