Metered Paywall for Gated Content

As a user, I want to be able to access gated content either by paying a small fee ($1) upfront or by reading a portion of the content for free, so that I can sample the content before deciding to pay for full access to additional resources.

Acceptance Criteria:

• Upfront Payment: Users should be presented with a clear option to pay $1 to access the full content immediately upon landing on the gated page.

• Metered Access: Users should be able to read a defined percentage of the content (e.g., 70%, 80%) without being prompted to pay.

• Paywall Trigger: After reaching the defined reading percentage, a clear and non-intrusive prompt (e.g., a modal or banner) should appear, offering the user the option to pay $1 to unlock additional resources.

• Content Differentiation: The initial free content should provide substantial value, while the additional resources (e.g., videos, downloads, further reading) should enhance the experience but not be essential for understanding the core message.

• Clear Messaging: The paywall prompt should clearly explain what the user gets by paying (i.e., access to the additional resources).

• Seamless Payment Integration: The payment process should be simple and secure.

• Post-Payment Access: After successful payment, users should have immediate and uninterrupted access to all content, including the additional resources.
