/* =====================================================================
   Header "···" dropdown — Dark Mode / Refresh Data / Sign Out

   The overflow button added beside "Need Help?" (Figma Navigtion_v2,
   17454:39408) opens this panel. Shared by every page in the flow that
   carries the header, so the rows, the switch and the motion live here
   once instead of in eight inline <style> blocks.

   Rows, icons and the destructive red follow the profile menu this
   prototype already ships in accounts copy.html — same 20px Phosphor
   glyphs, same #f7f9fa hover, same #d0134c for Sign Out — so the two
   dropdowns in the product read as one component.
