/* Mail Admin styles, loaded after Water.css (automatic light/dark build).
   Water styles plain elements; this file adds the two-column shell (menu on
   the left, pane on the right), compact sizing, coloured buttons, form grids,
   and stacked table rows on narrow screens.

   Colour scheme "Aurora": a midnight-navy menu column lit by a teal, violet
   and magenta gradient; a bright pane in light mode, deep indigo in dark
   mode. All colours are variables here; Water's own variables
   (--background-body, --border, --links ...) are overridden so plain
   elements follow the scheme too. Text/background pairs meet WCAG AA
   (4.5:1), input borders 3:1. */
