   Arcanium · Solid Text / Transition card (shared)
   The reusable "definition / segue / transition" text block — an
   eyebrow badge, a bold title, and body copy on a soft blue panel.
   Use it anywhere you need a self-contained chunk of teaching text
   or a transition between sections (mirrors the CAV Physiology
   clinical-anchor cards). Loaded globally; drop it in by markup:

     <div class="solid-text-card">
       <div class="solid-text-card__badge">Label</div>
       <h4>Bold headline statement.</h4>
       <p>Body copy. Inline <strong>bold</strong> and
          <span class="cav-term" tabindex="0" data-tooltip="…">terms</span> work.</p>
     </div>

   Optional: wrap in <article class="topic-section-card full-width">
   to get the white outer frame + page section spacing.
