A bunny hops where home links gleam,
The header now is sleek and clean.
No rebrand note shall crowd the way,
Just one homeward hop today.
Thump-thump—simpler code!

frontend/src/components/AuthHeader.tsx (1)

45-45: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Line exceeds 100-character limit.

The MarketingHomeLink className string on this line is well over the repository's 100-character line limit for TypeScript/React code. Consider extracting the class list into a constant or using template literals/cn() split across lines.

As per coding guidelines, "Use 2-space indentation, double quotes, and enforce 100-character line limit for TypeScript/React code" for frontend/src/**/*.{ts,tsx}.
