A piece of stone, shell, or contrasting wood cut to fit a recess in a larger substrate, set flush, polished to a single continuous surface. Reads as a graphic image in mineral / wood, durable for centuries. Pietra dura panels in Florentine cabinetry, turquoise channel-inlay rings, mother-of-pearl shell on guitar fretboards, marquetry on Art Deco furniture.
Substrate is recessed by hand-cutting (jeweler's saw, carving tool) or CNC to match the inlay's outline — clearance ~0.1 mm. Inlay piece is bedded with a setting compound (epoxy, two-part dental cement for stone; hide glue for traditional pietra dura; PVA wood glue for marquetry). Polished flush after cure. Stone-on-stone (pietra dura) uses local matrix of diamond or natural stone matched in hardness; metal-channel inlay uses a wall machined into the metal, the inlay tamped flush, the channel walls peened over to retain.
character — graphic image in inlaid material, flush continuous surface, traditional craft register.

Materials and processes for people who design and make things.
A local-first library of materials, processes, applications, and finishes — equal weight, citable everywhere, so a student can move from "what is this" toward "what's actually buildable here, now, by me." Part of the renato.design ecosystem — sibling of Plenum, Specimen, Ingenue, gesture, graf, and the Renato Rhino plug-ins. Form and matter, inseparable.
Half of teaching materials is teaching how the material is made into the thing. The standard subscription library was always light on that half. The wedge here isn't better samples or a prettier interface — it's treating Process as a peer entity, not a footnote.
