Make a flat surface that looks PRINTED ON a real material: a quote on a stretched canvas, a poster, a shop sign, a label, a plaque, a book cover. Start from a `base`: a texture set from the library (`setId` from list_assets; tiled at `tileSize` meters, or `mode` "stretch" for a whole-sheet scan), explicit `maps` {baseColor, normal, ormh} urls, or a flat `color`; `tint` re-colours the base and keeps its detail. Then `layers`, painted in order: text {text (use \n or | for line breaks), font typewriter|sans|horror, weight, size (letter height in meters), color, align, x/y (the block centre, 0..1 from left/top), maxWidth (share of the width; the size shrinks to fit), tooth (0..1, how much ink skips the low spots of the weave), dry (patchy ribbon), jitter (typewriter wobble)}; image {src (an /assets url), x, y, width (share of the surface width), opacity, blend normal|multiply}; stains {amount, color, scale, seed}; spatter {x, y, size, drips, color (blood by default), seed}; grime {edge}; fill {color, opacity}. Ink and spatter sink into the base relief, emboss its normal and read glossier than the base, so light rakes across it like the real thing. `output` "panel" (default) saves a thin box MODEL of width x height x depth meters, its face looking down +X like the library picture frames, with a phone-sized copy made automatically, and a model waits for its room so a many-room site stays light on phones; place it with the `place` op the result gives. `output` "material" saves a baseColor/normal/ormh set and returns `materialMaps` for apply_ops (it stretches once across a face, repeat 1). To fill a picture frame, measure the frame first (measure gives its opening) and make the panel about 0.2 m larger than the opening both ways, placed just behind the frame's front. Returns a small preview image of the surface.
