For each context window, apply:
window_i = general + contrast × (scene_i − general)
where general = the full-prompt conditioning (refined, with memory
applied). The character description cancels in the delta because it
appears in both scene_i and general; the push focuses on what is
unique to each scene (action, environment).
- contrast=1.0 → plain scene encoding (original behaviour)
- contrast=1.5 → default, 50% extra push toward scene content
- contrast=2.0 → classic contrastive (2×scene − general)
New parameter: transition_contrast (FLOAT, default 1.5, range 1.0-4.0)
on Refiner V2 and in Studio popup Refiner tab.
