Three-Layer Engine

Native dark mode forcing, generic CSS, and JS-assisted mutation observing — applied intelligently per site.

No filter:invert()

Never uses blind color inversion. Explicit color remapping preserves images, videos, and app functionality.

Site-Specific Overrides

CSS-only overrides for complex web apps, targeting safe selectors without breaking app JavaScript.

Zero Production Dependencies

Ships no npm dependencies. Pure vanilla JS with Manifest V3 APIs for maximum performance.
