/*
 * DreamIT Host layout and type overlay for SOGo 5.12.10's signed-in app.
 *
 * Colour is not done here. The palette is branding/theme/dreamit-palette.js
 * and the stylesheet generated from it replaces SOGo's theme-default.css in
 * the pilot image, so every Material component already paints in DreamIT
 * colours before this file loads. This file only refines layout, type and the
 * few states the palette cannot express: the oversized date in the top bar,
 * the current module's button, row states in the message list, the selected
 * folder, the empty reader and keyboard focus.
 *
 * Every rule targets markup that exists only after sign-in (the main toolbar,
 * the sidebar, the message list and reader), so nothing here reaches the
 * login page, which keeps its own overlay in dreamit-sogo.css.
 *
 * Text colours below are WCAG 2.1 ratios against the surface they sit on.
