/*
 * FinSight demo — stylesheet.
 * Carries the product's two-state visual language (see dashboard/render.py):
 *   stable    — calm: quiet slate, no accent. "Nothing needs you here."
 *   divergent — signal: an amber rail + dot. "A standing belief is contested."
 * Severity graduates the signal (low -> amber, high -> red). This is an
 * instrument for an analyst, not a marketing page: fast, legible, dense where
 * it earns it. Theme-aware, responsive, reduced-motion respected.
