/* ============================================================================
   obase-login.css - the OBase sign-in scene ("neural constellation").
   Shared by every app that uses it (it started as a copy in each app).

   Host setup, once in the app's <head>, after obase-theme.css:
     <link rel="stylesheet" href="_content/OBaseThemes/obase-login.css" />
     <script src="_content/OBaseThemes/obase-login-fx.js"></script>
   The page markup (class ob-ai-login and its children) stays in the app's
   Login.razor. Fonts: the headings ask for "Space Grotesk" and Inter, which
   the app loads (for example from Google Fonts); without them the browser
   uses Segoe UI or sans-serif.

   Accent-aware: every glow reads --obase-primary-rgb and the dark surfaces
   read the accent's dark ramp (both from obase-theme.css), so the scene
   follows the picked theme. The mesh canvas is driven by obase-login-fx.js;
   everything else is pure CSS. Collapses to the card alone under 860px.
