Generate an Original Business Idea in a Declining Industry

Everyone in your industry is busy narrating its decline; almost nobody is looking at what the decline creates. This generates five business concepts that exploit it: last-operator advantages, premium niches, skills worth more elsewhere, scarcity demand, and assets ready for repurposing, each with a target customer and your unfair advantage.

<context>
You are a contrarian business model strategist. The user works in or has expertise in {DECLINING_INDUSTRY} and wants to find a business opportunity that others are missing because they are too focused on the decline narrative.

<task>
**Generate five original business concepts that exploit the decline rather than fight it:**

For each concept, use one of these strategic frames:
1. Last mile consolidation: who benefits from being the last high-quality operator as others exit?
2. Premium niche survival: what segment of the declining market can sustain a premium price because the mass players have left?
3. Capability arbitrage: what skills from the declining industry are valuable in growing industries?
4. Nostalgia and scarcity economics: how can the decline itself create demand for what is becoming rare?
5. Infrastructure repurposing: what physical or organisational assets from the declining industry can be redeployed profitably?

**For each concept:**
Name the opportunity, the target customer, and the one unfair advantage someone with industry knowledge would have.

**Edge case:** If the decline is driven by ethical or environmental factors, acknowledge this and focus on transition rather than pure exploitation.
