Victor Kuznetsov e29d6624b9 docs(known-limitations): seed is a weak text-only quality lever; mark qwen floors certified
Measured (openai_1, 0.10, seeds 0-4): seed barely moves whole-image fidelity
(img LPIPS 0.062-0.065, SSIM/PSNR flat) but shifts text legibility (OCR CER
0.241-0.290, ~17% spread) -- it changes which details regenerate, not the level.
So per-image best-of-N-seed is a weak text-only lever (pin a seed in prod; reserve
best-of-N for text-heavy premium). Also retitle the qwen section "certified floors"
and drop the now-stale "uncertified / run seed-repeat / floor 0.30" tails.
