Layout for the receiver-facing pages migrated from EnvelopeGenerator.Web.
|
|
Mirrors the legacy MVC <body> structure: page content + sticky footer
|
|
with copyright link, language switcher and privacy link.
|
|
|
|
Cookie consent is reimplemented in Blazor (localStorage-backed) because
|
|
ASP.NET Core's <ITrackingConsentFeature> only works on the server side
|
|
and is awkward to integrate with InteractiveAuto rendering.
