/* Cockpit density chip — top-right control + popover menu.
 *
 * Plain-language: styles the small chip that lives in the topbar
 * and the popover menu it opens. The chip is intentionally quiet
 * (matches the existing topbar buttons in tone) and gets brighter
 * on hover. The popover sketches a tiny preview of each density
 * mode so a manager who has never seen the choice understands what
 * "Simple" vs "Standard" actually changes. Theme-aware: every colour
 * is bound to an existing Cockpit CSS var so dark and light modes
 * inherit the right palette.
