 - **Branch:** `main`, in sync with `origin/main`.
+- **TASK 21 — real logo + creator-hub About: SHIPPED** (this session). The About overlay is now the
+  **creator hub**: the real logo ("llama fortnite superman logo" copied from `\\llamavault` → `Assets/llama-logo.png`,
+  the creator's own art — no third-party license), plus hub links — **llama chile shop on YouTube**
+  (`MainViewModel.ChannelUrl`, public now), **Mastodon** (`https://mastodon.llamachile.tube/@gramps`),
+  **Buy me a coffee** (`https://buymeacoffee.com/llamachiley` — LIVE), and **Unlock Premium** (greyed
+  "coming soon"; the itch.io product URL is a **tabled seam**, `MainViewModel.PremiumUrl` — the itch.io
+  account was just created and needs a setup session later). **Licenses & legal** flips the About overlay
+  to an in-app scrolling panel loading the shipped `THIRD-PARTY-NOTICES.txt` (`ShowLicenses()` reads from
+  the executable dir on first open, graceful "not found" fallback — never the OS viewer); "← Back to
+  About" (`BackToAbout_Click`) returns. Integration test (ONE): `AboutHubTests` drives the real window,
+  asserting the hub opens, the link URLs are real, licensing loads the shipped notices text, and back
+  returns to the hub. **174 tests passing, 0 warnings.**
 - **TASK 8 — meter scaling amplification:** SHIPPED + pushed (`0b71b03`). `AudioLevelMeter.ToDisplay`
  adds **+10 dB input amplification** before the −60..0 dBFS log map: speech peaks (~0.2 RMS) read
  ~0.93 (red) and normal speech (~0.05) ~0.73 (yellow) at maxed volume; ≤0.001 linear still reads 0
