Modifications (CreativePower): imported on 2026-10-04 from the effects-staging run of gyng/ditherer @ fcf86f25dd9e. The effect's page runs on CreativePower's effect host (its speed, off-screen pause, render resolution and design tokens), its colours read the design tokens with its own values as fallbacks, and its main parameters are exposed as settings.
