Style references solve a core governance problem in AI image generation: maintaining visual consistency when multiple team members generate content. Without --sref, even identical prompts produce visually inconsistent results because aesthetic interpretation varies with each generation. A style reference anchors the visual treatment to a known baseline.
Professional teams build governed style kits — curated collections of approved --sref codes organized by tier (brand-core, project-specific, experimental). Each reference is tested against standard prompts to document its visual behavior. The challenge is that style references are opaque codes with no inherent description, so without a searchable library linking codes to visual examples, teams lose track of their approved styles within weeks.
