🛡️ Stricter Structure Detection & Anti-Cheat Improvements

The detection logic has been further tightened to provide a fairer experience, especially in multiplayer.

👁️ True Line-of-Sight Check

• Titles now only appear when the structure is actually visible to your character.
• No more titles popping awkwardly through walls or underground barriers.
• The visibility check runs server-side, offering an extra layer of anti‑cheat for multiplayer servers.

⛏️ Underground Depth Rule

• A new rule lets you define a minimum Y‑level under which a structure is treated as underground.
• Important: The mod uses keywords to classify a structure as underground — make sure your config aligns with your needs.

🚫 Tiny Structures Disabled

• Extremely small structures are now completely blocked from triggering titles at code level.
  Examples: Buried Treasure, Nether Portals, etc.
  This eliminates false positives and unwanted clutter.

These changes build on the earlier line‑of‑sight update and greatly improve server safety without compromising the mod’s core functionality.
