 * IntelligenceIndicator — single-element, three-stage design.
 *
 * Layers (always in the DOM, always at full opacity for layout
 * purposes — only individual properties animate):
 *
 *   • `__chrome`   — the glassmorphism pill (bg, border, shadow,
 *                    backdrop-blur). Absolute-positioned behind the
 *                    content. Visible while in-progress; fades to 0
 *                    once the icon morph completes.
 *   • `__content`  — icon + label flex row. Stays in place across
 *                    the whole transition. Only its `color` alpha
 *                    drops on settle (0.92 → 0.55).
 *   • `__icon-path` — single SVG path whose `d` morphs between a
 *                    270° arc and a checkmark. Both shapes share the
 *                    same 3-segment cubic Bézier topology, which is
 *                    what makes the d interpolate cleanly. The "spin"
 *                    is a marching-dash animation on the stroke, not
 *                    an SVG rotation — so there is no rotation state
 *                    to snap back to identity when the animation is
 *                    removed at status flip.
 *
 * Stage timing (hard sequence — stage 2 waits for stage 1):
 *   • Stage 1, icon morph: 0 → 250 ms.
 *       - d interpolates arc → check
 *       - stroke-dasharray transitions dashed → solid
 *       - marching-dash animation is removed (`animation: none`)
 *   • Stage 2, settle:     250 → 650 ms (transition-delay 250 ms).
 *       - chrome opacity 1 → 0
 *       - content color alpha 0.92 → 0.55
 *
 * Total ~650 ms in production. No moment exists where the icon or
 * label is invisible, so the eye never sees a "bump."
 *
 * Mount-already-finished is handled implicitly: CSS transitions
 * don't fire when the target value is the computed value at first
 * paint, so a historical-replay turn renders directly in its
 * settled state with no animation — which is the desired behavior.

   moment. A CSS transform applies after layout — no reflow — and
   interpolates over the same 400 ms / 250 ms-delay window as the
   color, so the slant and the color settle as one motion. For the
