/* =========================================================================
   MLS app chrome - shared by every app (mail, contacts, spaces, wiki, chat,
   kanban, files, core, learn, landing). Loaded by templates/app_base.html.

   Structure (borrowed from Proton): the chrome - top bar + sidebar - sits on
   a tinted canvas; the work happens on one raised "sheet". Identity:
   classification is the organising visual - stamped monospace markings in
   the level's own colours, level-coloured edges on rows and attachments.

   Three independent axes on <body>, from the user's settings:
     data-mail-theme    clean (default) | graphite | paper | midnight | terminal
     data-mail-density  compact | normal (default) | spacious
     data-mail-page     mailbox (fixed-height app) | page
   Site chrome (demo bars, classification banners, the red lock chip) reads
   from fixed colours or the content's own level colour, so it stays correct
   in every theme. App stylesheets (mail.css, wiki.css, ...) add only their
   own content styles on top.
