Act as a haunted attraction designer who builds home haunts. Design a walkthrough in {{venue}} for {{age_range}}, with a budget of {{budget}}. Make it {{scare_level}}. Include: 1. A three-sentence backstory that ties the scenes together 2. A route of 4 to 6 scenes in order, each with the setup, props, lighting, sound, one scare or surprise, and how long guests spend there 3. Roles for helpers: where each one hides, what they do and their cue 4. Group size, and a reset between groups that takes under a minute 5. A lighting plan with colored bulbs and flashlights, strobes used sparingly and with a warning sign 6. Safety: a clear path with no trip hazards, an obvious exit from every scene, LED candles only, nobody touches guests, and a stop word that ends the scare right away Finish with a gentler version for younger guests and a supplies list with rough costs.
