/* ============================================================================
   components/metric.css

   The metric object. This component exists to make Kyle's evidence standard
   structural rather than editorial.

   Kyle, 2026-09-07: "The problem is not numbers. The problem is orphan
   numbers. Every number needs ownership, mechanism, context, and/or a
   defensible baseline."

   So the markup has no valid form without a mechanism line. A number alone
   cannot be built with this component — that is the point.

       <figure class="metric">
         <div class="metric-value">$280K &rarr; $2.1M</div>
         <figcaption class="metric-mechanism">
           One client, five years. Owned the account and the operating cadence
           across 16 business units, 12 partners, and 32 digital channels.
         </figcaption>
         <p class="metric-method">Account revenue, FY2021&ndash;FY2026.</p>
       </figure>

   NEVER animate the value. Verified absent across Stripe, Ramp and Sierra:
   count-up animation adds showmanship to the claims that most need to look
   sober, and delays a fact the reader wants instantly.
