Use the @code{font-lock-fontify-region-function} hook similarly to

Somehow identify the multiline construct right when it gets inserted

Rely on @code{jit-lock-contextually}. This will only rehighlight the part

a short delay. This only works if the highlighting of the various
parts of your multiline construct never depends on text in subsequent
