"""
Fleet Resource Tracker — Tracks Capacity, Uptime, and Innovation.

Paperclips-inspired tension model:
- Capacity: spent on fleet improvements, generates through utilization
- Uptime: earned when services stay up, Fibonacci milestones unlock capabilities
- Innovation: only generates when capacity < 70%. Fuels Phase 3+.

This is the heart of the fleet progression system.
