Emerald Armor mod notes

• Adds an emerald gear tier (armor + full tool set) tuned between iron and diamond; gear repairs with emeralds and uses the standard crafting layouts.
• Items are placed into the Combat (sword + armor) and Tools (pickaxe/axe/shovel/hoe) creative tabs; item and armor textures are lightweight placeholders included in the assets.
• Emerald armor uses custom material stats (extra durability, 1.0 toughness, zero knockback resistance, improved enchantability) and emerald tools mine faster and last longer than iron while staying weaker than diamond.
• Wearing the full emerald armor set grants a mild, persistent villager trade discount (Hero of the Village style, low tier) that is removed as soon as a piece is taken off.
• Use by dropping the built mod jar into a Fabric 1.21 mods folder (client-side); crafting and anvil repairs both consume emeralds.
• Suggestions/limits: visuals are placeholder-simple; the set-bonus effect relies on applying the Hero of the Village status at base level—other active, stronger Hero effects are left alone.
