Honor the host OS instead of freezing or exempting animations in the shared theme.
These tokens are used by every view, so the comments should describe the layout primitive rather than the inventory dashboard that motivated the values.
A host sizes the iframe to its own panel, so a breakpoint never reports the display width. Claude's inline panel measures just under `lg`, which stacked three metric cards that had room to sit side by side.
The classes already show the row is container-sized; the Claude-panel anecdote does not belong on the component or in the shared README.

Summary
@transcend-io/mcp-ui-commonkit (Grid,Heading,MetricCard,ProgressBar,Spinner) withmakeEnumvariants. Spinner is a LogoSpinner-style port with its own CSS, inlined by the view build.discoverMcpAppViewsto@sourcethe kit only when a package declares it, so hello-world and other views do not pick up its CSS.lg, andmax-w-viewtokens. Card surfaces stay on Transcend light tokens (status colors have no dark palette yet). Comments describe the primitives, not a specific dashboard. Views follow the host/OSprefers-reduced-motionsetting.Test plan
