/* Usage and API Keys */
/* .management-view is a column flexbox (via .workspace-view); its direct
   children default to flex-shrink: 1, so on a short viewport the browser
   silently squeezes a card below the height its own content needs instead of
   growing the page. Since .content-card also clips with overflow: hidden,
   a squeezed card's overflow isn't just visually tight, it's invisible and
   unreachable -- no scrollbar appears anywhere to reveal it. flex-shrink: 0
   keeps every card and the summary grid at their natural height, so
   .management-view's own overflow-y: auto scrolls the page instead. */
