"""Artifact catalog parsed from WhiteDog1004/sephiria's artifacts.json.

Each entry exposes the fields we actually need for icon matching and
rendering: value (canonical key), Korean label, tier, and the CDN image URL.
The full effect text / description is kept opaque — the matcher only cares
about the image, and effects are not applied to the optimizer (slab effects
only, per existing design).
