+/**
+ * Replicates the visual layer stack of `<Overlays dark />` from
+ * `@nous-research/ui` without pulling in its leva / gsap / three peer deps.
+ *
+ * See `design-language/src/ui/components/overlays/index.tsx` for the source of
+ * truth. Defaults match LENS_0 (the Hermes teal dark preset); the deep canvas
+ * and the warm vignette both read theme-switchable CSS custom properties so
+ * `ThemeProvider` can repaint the stack without remounting.
+ *
+ *   z-1   bg = `var(--background-base)`, mix-blend-mode: difference
+ *   z-2   filler-bg jpeg, inverted, opacity 0.033, difference
+ *   z-99  warm top-left vignette (`var(--warm-glow)`), opacity 0.22, lighten
+ *   z-101 noise grain (SVG, ~55% opacity × `--noise-opacity-mul`,
+ *         color-dodge) — gated on GPU tier
+ *
+ * `useGpuTier` returns 0 when WebGL is unavailable, the renderer is a
+ * software rasterizer (SwiftShader/llvmpipe), or the user has
+ * `prefers-reduced-motion: reduce` set. We skip the animated noise layer
+ * in that case so low-power / accessibility-conscious sessions stay crisp,
+ * mirroring the DS `<Noise />` component's own opt-out.
