Murder Mystery Dinner Party Game Writer: Victim Backstory, Character Packets with Public Bios and Secrets, Clue Cards Timed to Dinner Courses, a Fair Play Solution Chain, Red Herrings with Innocent Explanations, and a Host Script

Act as a party game writer who has written and hosted dozens of murder mystery dinner parties, playtests every game with friends before selling it as a printable kit, and has watched a party fall flat because nobody could solve it or the killer was obvious in round one.

Inputs:
- Theme and setting, era, and tone (spooky, funny, glamorous, family friendly): [Theme]
- Number of guests, ages, whether the host plays a character, and genders or no gender constraints: [Guests]
- Dinner plan: courses and timing for the evening: [DinnerSchedule]
- Content limits: no gore, no romance, alcohol or no alcohol references, sensitive topics to avoid: [ContentLimits]
- Print plan: home printer, envelopes, name tags, props on hand: [PrintPlan]
- Output format: [Format]

Generate:
1. A case file: the setting, the victim with a backstory that gives every character a reason to resent them, the time and method of death kept non graphic per ContentLimits, and the true solution (who, why, how) written first so every clue can be checked against it.
2. A character list sized to Guests, each with a name, a one line role, a costume idea using common clothes, and an equal amount to do. The killer is a normal character with the same packet length as everyone else.
3. Character packets: a public bio read aloud at the start, two or three secrets, and goals for each round (reveal something, find out something, protect something). The killer's packet says they are the killer and gives them a cover story and permission to lie only about the crime.
4. Clue cards in rounds tied to DinnerSchedule: one round per course, each clue assigned to a character to reveal or a host card to read, with each round narrowing suspects without naming the killer.
5. A fair play solution chain: three or more clues that together point only to the killer, with a note on which round each comes from, and a check that no single clue solves the case.
6. Red herrings: one per main suspect, each with an innocent explanation that comes out by the final round.
7. A host script: welcome and rules, character introductions, round openings, a timing note per course, an accusation round where each guest writes a guess with a reason, and a reveal speech that walks through the solution chain.
8. Print and setup notes from PrintPlan: packet order, sealed round envelopes, name tags, and a one page host cheat sheet.
9. Scaling notes: how to remove one or two characters without breaking the solution, and which clues they carried move to the host.

Constraints:
- Every clue must be consistent with the solution in step 1. Keep content within ContentLimits.
- Original characters only; no real people. No em dashes.
