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.
Target: Season 3.
TMDB Season Synopsis: "Peabody and Sherman add big names to their ever-growing roster of guests, from Ada Lovelace and Frédéric Bartholdi to John Muir and Johnny Appleseed."
Source [1]: Title: The Mr. Peabody & Sherman Show (2015). Genre: Animation, Family, and Comedy. Description: The world's smartest dog and his boy host a zany late-night comedy show.
Source [2]: Title/Dates: The Mr. Peabody & Sherman Show (TV Series 2015–2017).
Source [3]: Description: The world's smartest dog and his boy host a zany late-night comedy show from a swanky penthouse, with time-traveling historical figures and a live audience.
Source [4]: Description: American animated jukebox musical comedy television series produced by DreamWorks Animation Television and Jay Ward Productions. Based on "Peabody's Improbable History" from The Adventures of Rocky and Bullwinkle and Friends.

Available Info for Season 3: Peabody and Sherman add big names to their ever-growing roster of guests, from Ada Lovelace and Frédéric Bartholdi to John Muir and Johnny Appleseed.
Problem: The provided synopsis for Season 3 is extremely short (one sentence). I cannot reach 160-220 words without inventing information, which is strictly forbidden ("You never invent or guess... If a detail is not in the provided material, you omit it rather than guess").
Constraint Check: "Write ONLY verifiable facts that are explicitly supported by the provided SYNOPSIS and SOURCES."
Dilemma: If I write only what is provided, the overview will be about 25 words. If I try to reach 160 words, I will violate the "do not invent" rule.
Resolution: In professional archiving, if the source material is insufficient to meet a length requirement, the archivist must prioritize accuracy over length. However, the prompt explicitly asks for a "factual 160-220 word summary".
