Guidance

One-time CSS import

Import the compiled stylesheet once at your app root: import '@orionshub/lucent/styles.css'. Components ship stable class names and read design tokens from CSS custom properties — there is no style runtime. See CSS Import.

Transparency & solid mode

Every glass surface reads --lucent-glass-opacity (0.60–1.0). Dial it at runtime with setGlassOpacity(), or switch to setContrast('solid') for a fully opaque, high-contrast rendering. See Transparency & Solid Mode.

Reduced motion

Animations are CSS-only and disabled under @media (prefers-reduced-motion: reduce). See Reduced Motion.

RTL

Authored with CSS logical properties — set dir="rtl" on a parent (or the document) and layout mirrors with no JS. Toggle RTL from the glass-controls panel to preview. See RTL Support.

SSR / Next.js

Client component — ships a "use client" boundary. All components are safe to import in a Server Component tree; interactive ones carry their own "use client" boundary. See SSR & Next.js.
