ImageJump changes: selection of five recipes and mapping to local preset
identifiers. The operation parameters are copied without modification. Runtime
intensity mixing and UI names are ImageJump features. Other OpenStill LUTs and
third-party film simulation assets are not included in this selection.

This notice records the existing public dedication; it is not a new personalized
permission letter from the upstream authors. CC0 does not imply endorsement.

LUT asset conversion: the five corresponding precomputed OpenStill Originals
CC0 tables were extracted by catalog byte range from the pinned Library.lutpack.
Only these five source-table slices are retained. The ImageJump offline generator
verifies the catalog's decoded-plane SHA-256, then converts normalized UInt16 RGB
values to little-endian Float32 RGBA with alpha 1.0. Lattice order is unchanged
(red index fastest). No third-party film-simulation tables are included.
