Lamb Lanterns is a small companion mod for LambDynamicLights. It lets you slot a vanilla lantern (or soul lantern) into a dedicated Lantern Curios slot — and then it actually behaves like one.

What it does

Adds a dedicated lantern slot to the Curios screen with a faded lantern silhouette icon. No fighting the belt slot for space with backpacks, rings, or charms.
Renders the worn lantern hanging from the player's right hip, with a chain attachment on the actual hip-bone of the body model.
Damped 2D pendulum physics: the lantern swings forward when you walk, side-to-side when you strafe, and gets a little kick when you start sneaking.
When LambDynamicLights is installed it emits real dynamic light through the LDL API — exactly as if you were holding the lantern.

Install on both server and client — the slot lives server-side (Curios is server-authoritative), the rendering and dynamic light are client-side.

Notes

The hanging lantern model is rendered with hanging=true, so it shows the chain even though it's not attached to a block above.
Items can be added to the slot from datapacks by tagging them #curios:lantern. They'll be storable but only vanilla lanterns get rendered on the body unless a third-party ICurioRenderer ships with the item.
Vanilla light is monochrome, so soul lantern light is white in vanilla. Shader packs that respect per-block emission tint will color it on their own.

Body-anchored rendering and the pendulum shape are inspired by ImmersiveLanterns by Toni — go check it out for a fuller take on lantern accessories.
