/* =========================================================
   FIX v3: Language dropdown layering on Book page
   Problem: dropdown appears but is rendered beneath other
   dark/sticky elements (looks like it's "hiding" under the
   black background). This forces the header + dropdown to
   sit above sidebar/content stacks and prevents clipping.

/* Sidebar should not cover header dropdown */
