Design review on the live canvas, not exported PNGs

The usual review loop: export six PNGs, upload to the thread, collect comments against stale images, export six more. By round three nobody knows which version anyone is looking at.

Instead, your Krita session runs in a container, and you drop one link in the channel: the display URL with ?readonly=true&sharing=true. Reviewers open it and watch the actual canvas: live, at full fidelity, while you work. You toggle a layer on and off; they see it flicker in real time. "Can we try it warmer" gets answered in fifteen seconds, on screen, instead of in tomorrow's export batch.

There is exactly one version: the one currently open.

Reviewers see the canvas, not an export of it.
