    - Added sci-fi flavored descriptions combining planet characteristics and materials.
    - Fixed base flamethrower turret subgroup assignment to keep it with MK upgrades.
    - Created missing recipe categories (electromagnetics, cryogenics) automatically.

Version: 2.1.0
Date: 2026-07-12
  Changes:
    - Fixed compatibility with Factorio 2.1: Changed recipe prototype field `category` to `categories` for MK3 and MK4 upgraded flamethrower turret recipes.
    - Updated recursive tinting logic to support the new 8-direction flamethrower turret sprites (north, north_east, east, south_east, south, south_west, west, north_west), ensuring correct mask coloring on all diagonal directions.

Version: 1.1.1
Date: 2025-06-13
  Changes:
    - Added item weights to upgraded flamethrower turrets based on rocket capacity reduction: MK1 62.5kg, MK2 83.333kg, MK3 125kg, MK4 250kg.
    - Weight progression follows the rule that each tier reduces rocket payload by 4 (from the vanilla 20 payload).

Version: 1.1.0
Date: 2025-06-06
  Changes:
    - Overhauled stats to match the Rocket Turret upgrade line: health (800-2000), range (+4 per tier, 34/38/42/46), damage multiplier (2/4/6/10), and fluid consumption (2.5/2.0/1.5/1.0/s).
    - Recipes updated with advanced Space Age materials: tungsten plates, tungsten carbide, superconductors, supercapacitors, carbon fiber, ammonia, quantum processors, promethium asteroid chunks, and cold fluoroketone.
    - MK3 and MK4 now require a cryogenic plant for final assembly.
    - Technology packs rebalanced to match the Gun Turret line: all tiers include space science pack; MK3 adds agricultural and cryogenic; MK4 adds promethium science pack.
    - Switched to recursive mask tinting for reliable coloring across all turret states (folded, preparing, attacking, etc.).
    - Added dynamic technology patch to automatically apply turret-attack bonuses from refined fuels research to all upgraded flamethrower turrets.
    - Polished and optimized custom item, entity, and technology icons.
    - Updated English and Chinese locale files with detailed descriptions.

Version: 1.0.0
