Season overview

Role: Meticulous television and film archivist.
Task: Produce a JSON object for "Code Lyoko" Season 3.
Keys: overview (160-220 word summary), primer (array of exactly 4 concise bullet points).
Constraints: Use ONLY provided synopsis and sources. No invented facts. No markdown. No asterisks. No headings. No bullet points in the overview (though the primer is an array). Output valid JSON only.
Input Material:
TMDB Synopsis: "As Season 3 opens, XANA has escaped from the supercomputer and is bent on destroying Lyoko so that the Warriors will be unable to stop his evil plots."
Source [1]: TMDB overview (incomplete: "Four children travel to the virtual wo").
Source [2]: IMDb (Four boarding school students discover a supercomputer in an abandoned factory, find a virtual world called Lyoko, awaken a sentient multi-agent system).
Source [3]: Wikipedia (French anime-influenced animated series created by Thomas Romain and Tania Palumbo, produced by MoonScoop).
Source [4]: Behind the Voice Actors (Release date Sep 3, 2003).
Source [5]: Moviefone (Full cast and crew).
Overview:
Season 3 starts with XANA having escaped from the supercomputer.
XANA's goal is to destroy Lyoko.
The purpose of destroying Lyoko is to prevent the Warriors from stopping XANA's evil plots.
Context from other sources: The series involves four boarding school students who discovered a supercomputer in an abandoned factory. This supercomputer contains a virtual world called Lyoko and a sentient multi-agent system.
Constraint Check: I need 160-220 words.
Problem: The provided text is extremely sparse. The synopsis is only 33 words. The IMDb description is about 45 words. I cannot invent details to reach 160 words. If I cannot reach the word count using only the provided facts, I must be careful not to hallucinate. However, the prompt says "factual 160-220 word summary". If the source material doesn't support that length, I have a conflict.
Re-evaluating the sources:
Synopsis: XANA escaped supercomputer, wants to destroy Lyoko to stop Warriors from stopping evil plots.
IMDb: Four boarding school students, supercomputer in abandoned factory, virtual world Lyoko, sentient multi-agent system
