• Supports of a higher track step two blocks sideways when they would pass through a track below. A short arm still holds the upper track.
• Upside-down track (local up pointing down) also places its supports beside the rail, not through the centre.
• Recipe book now unlocks Wood Track Ties and Steel Track Ties. All six craftable items already had shaped recipes.
• Added RECIPES_AND_COMMANDS.md with every crafting recipe and every /splinecart command.
