Lonsdaleite [ Tools/Armors/Weapons ] + Omnitool

Added

• Lonsdaleite Wardframe — a crystal frame block that only players may pass through.
  • Players, their tamed pets, and mounts/boats/minecarts carrying a player walk straight through; every hostile mob hits an invisible wall — and won't even try to path through the doorway.
  • Adjacent wardframes merge into a single frame: stack or tile them into doorways and gates of any size. Interior blocks of a large gate render fully open while staying mob-proof, and the frame redraws itself if a block is removed.
  • Crafted from a ring of 8 Lonsdaleite Gems (yields 8).
  • Blast resistance 1200 (creeper/TNT-proof), requires a diamond-tier pickaxe, emits a soft glow, and chimes like amethyst.
  • Discoverable by searching "door": tooltip text and the vanilla minecraft:doors item tag are plain data, so JEI/EMI/creative search all find it without requiring any mod.
