A distinctive SVG background of layered topographic contours that flow around configurable focal regions, thinning near a foreground safe area so text stays readable. Deterministic (SSR-safe), light/dark, reduced-motion-static, forced-colors-safe, offscreen-paused. No canvas, no WebGL, no heavy deps.
