1.1.1

• Restrict Fabric artifacts to their tested Minecraft versions, 1.20.1 and 1.21.1.
• Send modern explosion knockback as an additive impulse through the native explosion packet instead of replacing the client's velocity.
• Send each hit player's impulse before yielding the entity damage slice, so crowded explosions cannot delay client knockback across ticks. Send remaining observer effects once.
• Skip deferred observer effects after the recipient leaves the originating level, preventing ghost explosions in another dimension.
• Snapshot nearby effect recipients when calculation completes, before sliced entity damage, so observer movement and later level arrivals cannot change the audience.
• Deliver modern explosion sound and particles through that same packet, including nearby observers, without replaying block destruction or duplicating effects.
• Expand the README and add integration and usage guides with dependency setup, API examples and behavioral limits.
