2Point4 Children: Series 7

Season overview

Topic: 2Point4 Children Season 7.
Constraint 1: Use ONLY provided SYNOPSIS and SOURCES.
Constraint 2: No invented facts (titles, names, dates, etc.).
Constraint 3: Write original, neutral, encyclopedic prose.
Constraint 4: Output format: Valid JSON only.
Constraint 5: No markdown, no asterisks, no headings, no bullet points in the text content.
JSON Keys:
overview: 160-220 word summary of the season's narrative arc.
primer: Array of exactly 4 concise bullet points (though the instructions say "no bullet points" in the prose instructions, the JSON key asks for an array of 4 bullet points. Usually, in JSON, an array is the way to represent bullet points. I will provide an array of 4 strings).
Source 1 (TMDB): Series 7 aired 26th February 1998 to 9th April 1998. Seven episodes.
Source 2 (TMDB Overview): Average family. Stressed mum Bill, daft dad Ben, two troublesome teens. Crazy ideas, escapades, and mishaps.
Source 3 (IMDb): Starring Belinda Lang, Gary Olsen, Julia Hills, John Pickard. Follows the lives of the Porters; a seemingly average family whose world is frequently turned upside-down due to bad luck and bizarre occurrence.
Source 4 (JustWatch): Not available in US.
Overview: I need to write 160-220 words about Season 7's narrative arc.
Problem: The provided text does not contain any information about the narrative arc of Season 7. It only gives the air dates and episode count for Season 7. It gives a general series overview (the Porters, Bill, Ben, two teens), but nothing specific to Season 7's plot.
Constraint Check: "If a detail is not in the provided material, you omit it rather than guess." "Do not invent plot events or spoilers."
Conflict: If I cannot invent plot events, and the text doesn't provide Season 7 plot details, I cannot meet the 160-220 word requirement for the overview without violating the "no inventing" rule.
Wait: Let me re-read. "Series 7 of 2point4 Children first aired on 26th February 1998 with seven episodes finishing on 9th April 1998."
