# Hetzner Cloud catalog declaration consumed by fleet-protocol's Provider
# contract. Snapshot pricing in cents-per-hour (1 EUR = 10_000 Cents).
# Live prices come from the hcloud API via hetzner/nulib/hetzner/prices.nu;
# this file is the declarative reference the daemon and fleet-sim use when
# offline. Refresh periodically against the public Hetzner price list.
#
# Hetzner billing semantics (2026-05):
#   - Per-hour granularity, no per-second.
#   - Monthly cap at 730h (~30.4 days × 24h). Hours beyond that are free.
#   - Power-off still incurs charge for IPs + volumes but server compute
#     freezes — modelled here as stop_start_free=false (conservative).
