/* ==========================================================================
   DreamFundSL — Front page & sign-in
   Loaded after app.css and reuses its design tokens (--ink-*, --teal,
   --green, --gold, --parchment, --font-*). Nothing here changes the app
   shell; every rule is scoped to .auth-screen or the boot splash.

   Direction: the same digital-passbook idea as the rest of the app. The one
   memorable element is the sample "Financial health" passbook page: dotted
   leaders between label and value, and a total with a double rule under it,
   like the closing line of a ledger. Everything else stays quiet.
