Code Review

This pull request introduces two new documentation files, 'docs/scalable-application-structure.md' and 'docs/types-global-namespace.md', which outline the guidelines for a scalable feature-based application structure and a global types namespace. The review feedback suggests using a level 1 heading for consistency and correcting double spaces and first-person pronouns in the types namespace document to maintain a professional, objective tone.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
For more details on the timeline and next steps, please review the Help Documentation.

Use a level 1 heading (#) for the main title of the document to maintain consistency with other documentation files in the repository.

Suggested change

	## Types Global Namespace
	# Types Global Namespace

[gemini-code-assist]

The paragraph contains double spaces (e.g., cross-cutting global and extend the namespace) and uses the first-person pronoun 'I'. It is recommended to use objective, third-person language and correct the spacing for better readability.

Suggested change

	We designed a cross-cutting global project namespace to be easily reused across the project as a module encapsulating all the types in the application. I leveraged the inversion of control principle, so instead of defining all the types in one place (in the Types module), it's the responsibility of modules (which are owners of that particular type annotations) to extend the namespace.
