crudo
gioser-graph: exaggerated thickness & brightness, edges behind with pointer-events:none
1//! `gioser-graph-web` — grafo semántico SVG inline.
2//!
3//! Layout grid: 3 columnas, filas según cantidad de nodos.
4//! Nodos: rectángulos redondeados 170×44px con texto + subtexto (camino).
5//! Aristas: opacidad/brillo según weight (más peso = más blanca y opaca).
6//! Respiración CSS suave en el SVG (opacity oscila perpetua).
7//! Hover: glow + opacidad.
8//! Las aristas conectan por ID (UUID), no por doc_id.
