Standard Overlays & Menus
Undo Snackbar
A one-at-a-time bar for an action already taken — delete, archive, send — with a visible countdown and an Undo button that stays keyboard-reachable the whole window. Hovering or focusing it pauses the clock. Distinct from the toast queue: this holds exactly one reversible action, not a stream of notices.

Install it with velocityx add standard-undo-snackbar.
The CLI writes the source straight into your project — no runtime dependency, no registry
lock-in, and it themes itself from the same primary-*/accent-* scale as the rest of the library.

Confirmation dialog with least-destructive initial focus, async action support, Escape cancellation, and focus restoration.
reactA small marker pinned to a live element to flag something new or needing attention, that opens its explanation on click rather than hover. The badge itself persists until the user explicitly dismisses it, so a flagged field stays flagged until actually read, not until the cursor happens to pass over it.
reactMobile data-entry sheet with three drag snap points — peek, half and full — so the page stays reachable behind it instead of a full-screen takeover. Drag by pointer or step by keyboard, Escape to close, focus returns to the trigger.
reactOne step of a product walkthrough — a spotlight ring that tracks a live target element, a callout card with a step counter and Next/Back/Skip, fully keyboard operable. Escape always exits the whole tour, never just the current step, so a new user is never stuck in a walkthrough with no way out.
