Season overview

Role: Meticulous television and film archivist.
Task: Produce a JSON object for "SpongeBob SquarePants" Season 4.
Keys: overview (160-220 words), 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.
Source Material:
TMDB Synopsis: Mentions SpongeBob attending a party with Mr. Krabs' Navy buddies as Mr. Krabs, SpongeBob and Patrick making a movie, SpongeBob's quest to become King of Karate, and Patrick becoming Patricia.
Source [1]: Location is Bikini Bottom in the Pacific Ocean.
Source [3]: Series launched July 17, 1999. Cast includes Tom Kenny (SpongeBob) and Bill Fagerbakke (Patrick).
Source [4]: SpongeBob is a square yellow sponge living in a pineapple with his pet snail, Gary. He is a fry cook at the Krusty Krab.
Source [5]: Created by Stephen Hillenburg for Nickelodeon.
Overview: Needs to be 160-220 words.
Problem: The provided synopsis is very short. It only mentions a few specific episode plots:
1. SpongeBob attends a party with Mr. Krabs' Navy buddies while posing as Mr. Krabs.
2. SpongeBob and Patrick make a movie.
3. SpongeBob goes on a quest to become King of Karate.
4. Patrick becomes Patricia.
Constraint Check: I must write 160-220 words. However, the provided text is extremely sparse. If I only use the provided text, I will struggle to hit 160 words without repeating myself or violating the "do not invent" rule.
Wait: The prompt says "factual 160-220 word summary of this season's narrative arc." If the source material doesn't provide enough information to reach 160 words without inventing facts, I am in a bind. Let's look at the sources again.
Source [1] and [4] mention Bikini Bottom and SpongeBob's living situation (pineapple, Gary, Krusty Krab).
Source [3] mentions the launch date and cast.
Strategy: I will combine the setting (Bikini Bottom, Pacific Ocean), the character details (SpongeBob is a yellow sponge
