/* ==========================================================================
   Orbit design system — shared core

   This block is identical in Orbit AI (static/css/app.css), Orbit Mission
   Control (static/css/auth.css) and Orbit Mail (static/css/mail.css), apart
   from the .brand__logo rule noted below. Each app appends its own
   components after it. Keep the copies in sync.

   Direction
   ---------
   Monochrome. Light mode is white paper with black ink and a black accent;
   dark mode is true black with white ink and a white accent. Neutrals carry
   no hue at all, so the only colour on the page is semantic status (danger,
   success, warning). The brand mark is rendered black on light and white on
   dark. Everything else is quiet.

   Theming follows the operating system by default; the theme control sets
   `data-theme` on <html>:

     (no attribute)      -> follow the system
     data-theme="light"  -> force light
     data-theme="dark"   -> force dark

   Dark values are defined twice on purpose — once for the system preference
   and once for the explicit override — so the two can never drift apart.
   Every text token clears WCAG AA (4.5:1) on the surfaces it is used on.

/* ==========================================================================
   Orbit Mail — application components

   Layout follows Outlook: a thin app rail on the far left (Mail / Calendar /
   Admin), a folder pane, the conversation list, and a reading pane, with a
   command bar across the top of the list and reading pane.

   The theme is the shared monochrome one. The command bar is the one black
   surface in light mode (white ink on #111, like Mission Control's entrance
   panel); in dark mode it sits one step off the page black and takes a
   hairline. Sender avatars and the default calendar colour are neutral so
   the only colour in the window is semantic status and the calendar swatches
   people choose themselves.
