/* ============================================================
   BUREAU OF LOST TIMELINES — IDENTITY DESK SHEET
   Version: 2.0 (Dossier system)

   css/avatar.css owns one thing: the upload sheet js/avatar.js raises over
   the personnel file when an operative presses the pencil on their
   identicon. It is a stamped page from the same stack as the advisory
   dialogs — spine on the left, ink under the fibre, a single red action —
   and it is the only place in the Bureau where a member is allowed to
   alter their own record.

   The modal sits at z-index 10000 on purpose: css/ui.css raises its dialog
   layer to 20000 because a notice can appear from inside this sheet (the
   "Avatar saved" confirmation), and that notice has to land on top.
