TASK 21: real logo + creator-hub About overlay — the About overlay is now the in-app creator hub: real logo (the creator's 'llama fortnite superman logo' copied to Assets/llama-logo.png, creator-owned art), hub links — llama chile shop on YouTube (MainViewModel.ChannelUrl, now public), Mastodon (https://mastodon.llamachile.tube/@gramps), Buy me a coffee (https://buymeacoffee.com/llamachiley, live), Unlock Premium (greyed 'coming soon'; IsPremiumAvailable flips on once the tabled itch.io PremiumUrl lands); a Licenses & legal sub-panel loads the full shipped THIRD-PARTY-NOTICES.txt in-app (ShowLicenses reads from the executable dir on first open, 'not found' fallback — never the OS viewer) with '← Back to About' (BackToAbout_Click) — the AboutHubTests integration test drives the real window + VM asserting the hub opens, link URLs are real, licensing loads the shipped notices text, and back returns to the hub — 174 tests passing, 0 warnings
