/* SignalProbe — the live provisional-signal widget (S80 dark single-accent).
 * The alive moment. Elevated on --surface-2; the card BLOOM scales with the real
 * computed confidence via --signal-glow (set by js/signature-live.js — no
 * perpetual timer). The instrument reads as data via mono + tabular figures +
 * the warm value-ramp bars; the lean / confidence climb is the single lime
 * accent (with glow). No second hue.
 * Canonical: components/primitives/SignalProbe/SignalProbe.css */
