Role: Meticulous television and film archivist.
Task: Produce a JSON object for "Celebrity Antiques Road Trip" Season 11.
Constraints:
Use ONLY provided SYNOPSIS and SOURCES.
No invented facts (titles, names, dates, counts, awards, etc.).
If not in material, omit.
Style: Original, neutral, encyclopedic prose, plain text.
No markdown (no asterisks, no headings, no bullet points in the text).
Format: Valid JSON only.
JSON Keys:
overview: 160-220 word summary of the season's narrative arc.
primer: Array of exactly 4 concise bullet points (though the prompt says "no bullet points" in the prose instructions, it asks for an "array of exactly 4 concise bullet points" for the JSON key primer. In JSON, an array is the structure. I will interpret "no bullet points" as applying to the prose within the strings, but the array itself satisfies the "4 bullet points" requirement).
