Review

This is a clean, minimal fix for the duplicate site name issue.

The change is correct and well-scoped. The ternary on line 17 handles the edge case without touching anything else.

One minor note: the fix is string-equality based, which works perfectly here since the home page title is literally set to SITE.NAME. If a future page happened to use the site name as its title for some other reason, it would also skip the suffix — but that is almost certainly the right behavior anyway, so no action needed.

Test plan looks good. Approve when both checklist items are verified.
