Stage Auth Middleware

The `stage-auth-middleware` package provides an Express.js middleware specifically designed to secure staging environments for Akarion-related websites. Its core function is to enforce user authentication for access to stage URLs, thereby restricting public access, and to display a visual hint on the page indicating that the user is currently interacting with a staging site. The package is currently stable at version 1.0.9. It operates with an irregular release cadence, likely aligned with internal development cycles rather than public feature rollouts. This utility is highly specialized, serving a niche within the Akarion ecosystem, and should not be considered a general-purpose authentication solution. Its primary differentiator is its tailored integration with specific staging security requirements, offering a streamlined approach without the overhead of more comprehensive identity management systems.
