/* disclose.css — collapse-by-default disclosure for reference text.
   Native <details>, so it needs no JS and is keyboard-accessible.

   Use for methodology notes, citations, and "why this matters" copy —
   never for warnings someone needs before acting. When the hidden text
   carries a caution, put that caution in the <summary> line itself.

   <details class="ba-disclose">
     <summary>Kegels aren't right for everyone</summary>
     <div class="ba-disclose-body">…</div>
   </details>
