Discovery call opener that earns 30 seconds of attention

Help me draft the first 90 seconds of a discovery call. The prospect agreed to 30 min but is busy and skeptical.

Context:
- Company I'm calling: {{prospect company + their industry}}
- Their role: {{role + how senior}}
- What we sell: {{your product, one sentence}}
- What I think their pain is: {{your hypothesis}}

Output:
1. **The opener** (15 sec) — earn attention with a specific observation, not "thanks for your time"
2. **The frame** (30 sec) — what this call is and isn't, set expectations
3. **The first real question** — open-ended, gets them talking about their problem (not pitch-prep)
4. **What I should listen for** — 2-3 signals that mean "qualified," 2-3 that mean "this isn't a fit"

Don't write me a pitch. Write me a conversation starter.
