/**
 * Modal chrome and the verified-source evidence panel.
 *
 * The modal reproduces Streamlit's [data-testid="stDialog"]: a blurred scrim
 * that fades in, over a dialog that scales up on the spring curve, capped at
 * 38rem wide and 60vh tall with the accent aura painted into its background.
 *
 * The evidence rules below are the source's own, verbatim - the panel is built
 * from the same .evidence-meta / .evidence-chip / .evidence-section /
 * .evidence-passage structure that render_evidence_meta() and friends emit.
