### Problem `TabButton` and `AvatarOrIcon` stories (in both `twenty-ui` and `twenty-ui-deprecated`) used random remote image URLs — `picsum.photos/192/192` and `i.pravatar.cc/300`. Each Argos run fetched a different image, producing false-positive pixel diffs. This is the image counterpart to #21412, which froze framer-motion animations for the same reason. ### Fix Replace all 6 random URLs with `AVATAR_URL_MOCK` — a fixed base64 data URI already used across avatar stories. It's deterministic and network-free, so screenshots are now stable across runs. - `twenty-ui` / `twenty-ui-deprecated` → `TabButton.stories.tsx` (×2 each) - `twenty-ui` / `twenty-ui-deprecated` → `AvatarOrIcon.stories.tsx` (×1 each) Note: this changes the rendered image content, so it adds new baselines (one-time Argos approval, not flakiness).
