Problem:
docs/modules/serialization.mdx contains multiple “Example coming soon” placeholders (e.g., lines 22, 76, 114, 157, 206), leaving readers without runnable guidance on persistence APIs.

What to do:

• Produce Python and TypeScript snippets that mirror each described scenario (basic save/load, versioning, partial restores, encryption, etc.).
• Embed the examples in the doc using the existing pattern and link to source files under python/examples and typescript/examples.
• Validate instructions so users can copy, run, and see expected console output.

Acceptance:

• Every placeholder is replaced with working code and brief narrative that clarifies prerequisites and expected results.
