VR Office: Persist avatar selection and profile

Why

• Ensure consistent identity across sessions.

How (Implementation sketch)

• Store avatar URL and display name locally; add reset button.

Definition of Done

• Code committed with minimal docs/tests.
• If client work: sample scene or prefab updated and runnable.
• Errors surface to logs/toasts; no silent failure.
• Meets privacy defaults (no content capture, aggregates only).

Acceptance Criteria

• Rejoin loads same avatar; reset restores default.

Notes

• Each new Unity C# script or module ≤ 200 LOC (except generated code); keep functions short & single-responsibility.

Implementation Guidelines

Code Quality Standards:

• Each new script/module ≤200 LOC (single responsibility principle)
• Use meaningful variable names (no single letters except loop counters)
• Add XML doc comments for public methods
• Follow project naming conventions (PascalCase for C#, camelCase for TS)

Testing Requirements:

• Unit tests for business logic
• Integration tests for API endpoints
• Manual testing checklist in PR
• Performance profiling if affecting critical path

Documentation:

• Update relevant README.md files
• Add inline code comments for complex logic
• Document any environment variables or config changes
• Update API documentation if adding/changing endpoints

Dependencies:

• Check Prerequisites section in main README
• Document any new package dependencies
• Verify compatibility with existing stack
• Update lock files (pnpm-lock.yaml, Packages/manifest.json)

Review Checklist:

• Code follows style guide
• Tests pass locally
• No console errors/warnings
• Performance acceptable (profile if unsure)
• Documentation updated
• PR description explains changes clearly

Common Patterns: See /vr-office/docs/patterns/ for:

• Unity component patterns
• API service patterns
• React component patterns
• Error handling patterns
