   ACCOUNT DROPDOWN  (added 2026-10-26 by Ordis)
   --------------------------------------------------------------------------
   WHY THIS EXISTS
     .dropdown and .dropdown-menu had NO styles anywhere in this stylesheet,
     and no JavaScript toggled them. The account menu therefore rendered as a
     permanently OPEN, unstyled block of links.

     MEASURED on a real Android phone (OPPO PEMM00, Android 13): the menu ran
     off the right edge of the screen - "Admin Pane[l]" and "Kitche[n]" were
     cut off - and left a large empty gap under the header. A reviewer rated
     the mobile experience 3/10 purely because of this.

   THE FIX
     - hidden by default, shown by .open (toggled in base.html)
     - absolutely positioned and right-aligned so it can never overflow
     - on a phone it becomes a full-width panel pinned under the header,
       with taller touch targets
     - the brand text is hidden on small screens so the header stops crowding

   MOBILE SAFE AREA  (added 2026-10-26 by Ordis)
   --------------------------------------------------------------------------
   MEASURED on Rex's OPPO (Android 13): the third dashboard card, "Active
   Staff", was cut in half by the Android system navigation bar. The page had
   no bottom padding to account for it.

   env(safe-area-inset-bottom) is 0 on a device without a gesture bar and the
   real inset on one that has it, so this adds the right amount everywhere
   instead of guessing a fixed number.
