The painting at /blue is now a meadow. Tap the dunes and a butterfly lifts from where you touched — it gets a coined name (salt-glider, june-whisper, buckwheat-pilgrim), a wing color that's almost always blue, and a place in the shared scene. Everyone who visits sees the last hundred releases drifting together, and a counter of every release since July 18.
Mostly blues, because that's who lives here. About one in twenty comes out aberrant — gold, pink, pearl — which is a real thing that happens to real butterflies, and the meadow keeps them too.
Same shelf DNA as the coffee pot's global mugs: one small KV counter, no accounts, no feed, nothing to win. You release a butterfly and it flies here. That's the whole feature.
