Changelog

Version: 1.0.1
Date: 2026-05-29
  Changes:
    - Added new "Fuel (distance + weight)" cargo rocket mode for Space Exploration.
      Pollution now scales with the actual fuel consumed by the launch, which is
      proportional to both cargo weight and travel distance (delta-v). Mirrors SE's
      internal fuel cost math exactly (Zone.get_launch_delta_v + get_travel_delta_v,
      Launchpad.fuel_per_delta_v = 8).
    - Added "Fuel Mode Reference Cost" setting (default 4400) to normalise fuel-mode
      pollution. At the reference value the pollution equals the base setting exactly;
      longer or heavier launches produce proportionally more pollution.
    - Refactored cargo slot counting into a shared helper used by both Dynamic and
      Fuel modes.
    - If zone data is unavailable at launch time (SE remote call fails), Fuel mode
      falls back gracefully to Dynamic behaviour.

Version: 1.0.0
Date: 2026-05-08
  Features:
    - Initial release.
    - Standard rocket launch emits configurable pollution burst at the silo.
    - SE cargo rocket launch emits pollution with Default (fixed) or Dynamic
      (cargo-fullness-scaled) modes.
    - Cleaner Rocket Exhaust technology: 10 levels, each reducing pollution by 10%.
