Krea 2 V9 reference-conditioning nodes: guide cards assign each
reference image a role (identity, style, lighting, composition,
text/logo safe, and more) and the stack encoder builds Krea
conditioning with per-card strength, per-layer gains, and guarded
prompt handling. Includes the kg_krea_v9 package, web extension,
example workflows and assets, contract tests, and full documentation
with the technical paper.
Prior development history is summarized in CHANGELOG.md (0.1.0-0.1.5).
