layout.init()dispatches themashlib:layoutchangeevent immediately (during module init), butsyncEnvironmentToContext()depends on an outliner created later bypanes.initMainPage. This means the initial page load will reliably emitconsole.warn('outliner not ready yet'). Consider delaying registration of the layoutchange listener until afterinitMainPage(or makingsyncEnvironmentToContextsilent until the first successful sync) to avoid noisy logs.
