All speckles continue through the material thickness and appear naturally sliced at edges. The recessed glass channels are large, simple and fluid rather than numerous:
smooth curved paths, softly rounded interiors, real optical depth and faint frosted haze. The contrast must be tactile and clear—dry matte silicone versus cold translucent glass. Add slight silicone compression around channel edges, tiny pigment irregularity, fine molded texture, microscopic glass bubbles and restrained handling wear.", "detail_control": "Keep all source text and logos in uninterrupted silicone zones.
