documenso/examples — reverse-engineered prompt

Build me a small examples repo that shows real world ways to embed Documenso into apps. I want a few polished demo apps, not a full product. Include a gym membership signup flow where one person signs a generated document, a SaaS sales flow with instant template signing, a freelance contract flow with multiple signers and clear status tracking, and both basic and advanced document authoring so someone can create and edit documents and templates right inside the app.

Also add one simple Python Flask example that takes form data, generates a PDF on the fly, and places signature and date fields wherever placeholder text appears in the PDF.

Please keep the focus on the Documenso embedding experience and the different token based flows, not on deep business logic. Use simple sample data and clean UI so each example is easy to understand. If there are shared patterns between the demos, reuse them so the whole repo feels consistent. Look up the current Documenso embedding and API docs online if you need to.
