+### Shared equipment profiles
+
+Configuration inherited by every item of a finite equipment type belongs in a
+collapsible shared-profile registry above the item table. Each profile card
+states its type, required slot count, configured state, and a compact summary;
+selecting it opens a separate dense editor and closes the individual-record
+editor. Successful saves close the profile editor and return to the registry.
+
+Gear Tactical Augment profiles use this pattern for all six gear types.
+Backpacks and Body Armor expose four required slots; Holsters, Gloves, Knee
+Pads, and Masks expose three. Every slot contains exactly one searchable
+Attribute relationship, one numeric effect value, and one non-negative
+whole-number unlock cost. At narrow widths profile cards and augment editor
+cards reduce from multi-column grids to a single column while retaining
+44-pixel interactive targets.
