+## Luminar looks (`.lmp`, `.mplumpack`)
+
+`preset.import` (and drag & drop, File ▸ Import Profiles & Presets…) also reads Luminar looks: an `.lmp` file is an
+XML property list of adjustment layers (each with effects and named sliders, mostly on a −100..100 scale); newer looks
+may be a bundle folder `Name.lmp/Contents/preset.lmp`. An `.mplumpack` collection is a zip of `.lmp` files whose
+`PresetsInfo.plist` names the group (`GroupName`); the pack's file name is the fallback. Looks get their own name
+(`Name`) or their file / bundle name. The sliders with a clear counterpart are carried over; everything else (AI tools,
+Orton, glow, LUT layers, colour balance…) is listed in `unmapped` as `Tool.Slider` (e.g. `OrtonFilter.Amount`).
+Disabled layers are ignored, layer opacity scales the sliders (and fades curves toward a straight line), and layers
+with a blend mode other than Normal or with a mask are reported, not applied. Binary property lists are not read.
