v1.1.1

One fix, for anyone using the phone viewer away from a fast connection.

A scene is no longer downloaded twice. A phone that goes into standby has its tab evicted, and coming back meant fetching the whole scene again — eleven megabytes, over whatever connection happens to be there. The file was cacheable all along and nothing said so, which left the decision to whatever each browser inferred. It is now stated outright: a scene never changes once it exists, so it may be kept for a year. Returning from standby should now show the picture straight away rather than the download bar.

Also fixed, and the half more likely to have caused trouble later: the address the viewer polls to notice a new scene is now explicitly not cacheable. It never was cached in practice, but nothing had said it must not be, and a browser that decided otherwise would have pinned the page to whichever scene was current when it first asked — with no scene made afterwards ever appearing.

Nothing else changes. If v1.1.0 works for you on a fast local network, there is nothing here you need.

The full description of what this project is, and the two external conditions worth reading before installing, are in v1.0. What changed in the phone viewer itself is in v1.1.0.
