/* Blackties Dashboard — sign-in screens, styled to match blackties.co.uk.

   Deliberately scoped to `main.auth` (the signed-out shell in base.html), so the
   signed-in dashboard keeps its own gold theme untouched. Fonts are self-hosted
   because the app's CSP is default-src 'self' and Google Fonts would be blocked.

   Palette lifted from the website's stylesheet: ink #0b0a12, brand primary
   #4A068F, the vivid #9F43FE used on the wordmark, and the lifted #b78af0 for
   text on dark. */
