/* Magogi operator-instrument layer
 * ============================================================================
 * The control-surface components for MGF's operator tools (federation control,
 * the testing/CI authority, …): state chips, live indicators, progress, tabs,
 * the dark streaming console, authority markers, ribbons, the telemetry
 * live-pane, the per-test config panel, level badges, reference pills, detail /
 * evidence blocks and honest-absence empty states.
 *
 * Distilled from the mgf-fed-web + Proofwarden wireframes onto the SAME brand
 * tokens as the rest of the kit (tokens.css), so every operator surface reads
 * identical and inherits dark mode + reduced-motion for free. ADDITIVE: this
 * file introduces only new classes; it never touches the base / component layer.
 * Depends on tokens.css; load AFTER components.css.
 *
 * Colour policy (D-BRAND-ACCENT, locked):
 *   GOLD   (--color-accent)   — the ONE affirmative action per view (use the
 *                               kit's .button-accent; instruments never re-defs
 *                               a primary button and blue is NEVER a CTA).
 *   BLUE   (--state-busy)     — functional "busy / running" only.
 *   VIOLET (--state-derived)  — functional "derived / authority / telemetry".
 *   success / warning / error / info tokens carry the rest of the state language.
 * ============================================================================ */
