/**
 * citizen-copilot-shell.css
 * Responsive dockable citizen-action copilot shell.
 *
 * Desktop: left/right dock rail (layout side-rail, not overlay).
 * Compact: full-width canvas + collapsible drawer below breakpoint.
 *
 * No external URLs, no analytics, no persistence.
 *
 * Visual primitives are defined once in citizen-shared-tokens.css and
 * consumed here via assistant-specific aliases. The shared layer provides
 * assistant colors, typography, the radii actually used by the assistant,
 * the focus-ring geometry, status colors, transition timing, and the
 * reduced-motion collapse. This file MUST NOT change any resolved value.
