Published DS package · Pattern Library · Rottay / modernShared route metadata for the active runtime, kept inline so the shell reads like a thin header band.
Responsive feedback flow that selects modal, drawer, or sheet posture
Feedback patterns should adapt interruption and confirmation posture without changing the task contract.
How to read this pageUse the showroom switchers in the sidebar to change engine and tenant. The comparison grid below keeps the active tenant and swaps engines so we can inspect the pattern instead of page-local editorial chrome.
Live preview
Compare the same pattern across engines
Sidebar tenant drives thisAdaptive Overlay
This comparison is the documentation surface. If the pattern only reads well inside local chrome, we should fix the pattern or its preview runtime before teams style around it.
Preview heuristics
3 items
Compare density, action placement, and state readability before aesthetic flavor.
Judge the pattern itself, not any showroom-local framing around it.
If the pattern only works with extra chrome, the pattern or preview runtime still needs work.

Consumption
Import and usage
Treat the pattern as a reusable task contract. Keep route-specific business rules outside and use these snippets as the fast-reading baseline.

Usage notes
3 items
Import from the published package rather than building route-local wrappers first.
Pass data, config, and callbacks while keeping product semantics in the consuming app.
Escalate to a surface only once the whole screen contract is stable, not just the task module.

Engine comparisonEngine comparisonThe active tenant stays real while the same component is rendered by every engine. The wrapper stays intentionally quiet so engine differences come from the DS itself.
