Role: Meticulous television and film archivist.
Task: Produce a JSON object for "Heart Signal" Season 7.
Keys: overview (160-220 words), primer (array of exactly 4 concise bullet points).

Input Data:

Genre: Dating social reasoning reality show.
Platform: Launched by WeTV.
Setting: Greater Bay Area.
Theme: Exploring cross-city romance.
Note: The sources provide very little detail for a 160-220 word summary. I must be careful not to invent anything.
Wait, the prompt asks for a 160-220 word summary. If the provided text is only ~30 words, and I am forbidden from inventing facts, I cannot reach 160 words without violating the "never invent or guess" rule.
Self-Correction: The instructions say "Write ONLY verifiable facts that are explicitly supported by the provided SYNOPSIS and SOURCES." If the source material is insufficient to meet the word count requirement, I must prioritize the "ONLY verifiable facts" rule over the word count requirement, or find a way to expand using only the provided facts. However, expanding "Heart Signal S7 is a dating social reasoning reality show launched by WeTV. This season, it starts anew in the Greater Bay Area, exploring cross-city romance!" to 160 words without inventing anything is impossible.
