docs: icon-attractor section + 12 viral scroll-video prompts (leans on ERNIE's text-in-image strength)

docs: add prompting guide + simple-vs-ideal prompt table (Mistral3 encoder; quote-text for in-image rendering)

docs: declare SFW-by-default safety policy + reference safety_negative_prompt.txt

feat: ship default safety negative prompt for SFW-by-default consumers

docs: VAE is ERNIE's own 32-ch AutoencoderKLFlux2, not Flux's 16-ch ae

fix: replace Flux 16-ch VAE with ERNIE's actual 32-ch VAE (sd.cpp load failure)

engine renamed: KilnImage → Mirage
