/* iVega Agent Operations — design system.
 *
 * Written mobile-first: the base rules describe the phone, and the media
 * queries progressively add space rather than trying to squeeze a desktop
 * layout down. Navigation genuinely changes shape (bottom tab bar on a phone,
 * a persistent sidebar from 880px), because a shrunk sidebar is not a mobile
 * interface.
 *
 * The visual language is deliberately quiet. Colour is reserved almost
 * entirely for agent status, so that a red or amber badge is the only thing
 * competing for attention on a screen the operator may be scanning in seconds.
