No, because volume happens inside guardrails, not instead of them. The angle catalogue, the claims, the tone and the visual system are agreed with you up front; what varies at speed is the expression, hooks, formats, openers, not the brand.
In practice performance creative sharpens brands more often than it dilutes them: you learn, with receipts, which version of your story the market actually believes, and that learning flows back into everything else you make.
The guardrails are written down before production starts: claims that are in and out of bounds, tone, visual system, and the words the brand never uses. Every batch passes that gate before launch, so speed never gets to outvote the brand.
