mkdocs.yml (2)

64-66: Overview section properly nested with Features and Architecture.

The Overview section has been correctly restructured to include Features and Architecture as child pages. The documentation files exist at the expected locations (docs/overview/features.md and docs/overview/architecture.md), and the sidebar navigation configuration properly establishes the hierarchy to make these sub-pages discoverable.

---

67-70: Setup section correctly groups all setup guides.

All three documentation files referenced in the Setup section exist at the expected locations:

• setup.md (Quick Setup) ✓
• Manual_Setup_Guide.md (Manual Setup) ✓
• Script_Setup_Guide.md (Script Setup) ✓

The Setup section restructuring provides consistent sidebar behavior and improves discoverability of setup documentation.

docs/index.md (1)

70-71: LGTM! Frontend link correctly points to existing documentation.

The link has been correctly updated to target ./frontend/screenshots with the text "Screenshots", aligning with the documentation structure defined in mkdocs.yml. The change improves navigation consistency by maintaining a proper reference to the existing screenshots documentation.
