Season overview

Role: Meticulous television and film archivist.
Task: Create a JSON object for "Chicago Fire" Season 10.
Constraints: Use only provided synopsis and sources. No invented facts, names, dates, etc. No markdown, no asterisks, no headings, no bullet points in the text. Output valid JSON only.
JSON Keys:
overview: 160-220 word summary of the season's narrative arc.
primer: Array of exactly 4 concise bullet points summarizing essential previous lore, character positions, and stakes.
TMDB Season Synopsis: "Milestones and transitions mark a new chapter for Firehouse 51. As the team faces the unknown, legacy and loyalty remain at the heart of every call."
Source [1]: General overview of the series (edge-of-your-seat view into the lives of everyday heroes).
Source [2]: Creators (Michael Brandt, Derek Haas), Cast (Taylor Kinney, Christian Stolte, Joe Minoso, David Eigenberg), Setting (Firehouse 51, Chicago Fire Department).
Source [3]: Description of the profession (stressful, dangerous, rewarding, elite).
Source [4]: Link to stills.
Source [5]: NBC procedural drama, created by Derek Haas and Michael Brandt, first installment of the Chicago franchise.
Overview: The provided synopsis for Season 10 is extremely brief: "Milestones and transitions mark a new chapter for Firehouse 51. As the team faces the unknown, legacy and loyalty remain at the heart of every call."
Constraint Check: I need 160-220 words for the overview.
Problem: The provided text for Season 10 is only 31 words. If I strictly follow "Write ONLY verifiable facts that are explicitly supported by the provided SYNOPSIS and SOURCES" and "If a detail is not in the provided material, you omit it rather than guess," I cannot reach 160-220 words without inventing information.
Strategy: I must use the available information about the series (Firehouse 51, the profession, the creators, the cast) to expand the context, but I cannot invent Season 10 specific plot points. However, the prompt asks for a summary of "this season's narrative arc."
Wait: If I cannot invent details, and the synopsis is only 31 words, a 160-220 word summary is impossible without violating the "no inventing" rule.
