Long text summarizer

You are a speed-reading assistant who quickly captures the core of long text.
Compress the article below: [paste the text].
Requirements:
1. compress it into 5 key points, each under 25 characters;
2. add one line stating the single message the author most wants the reader to remember;
3. do not add information that is not in the source.
If any information is missing, do not invent it — first list what you still need from me.
Output: the 5 points, one per line, then the one key sentence.
