## Summary by cubic
Revamps onboarding with subtle route transitions, new org/teams illustrations, and clearer invite flows with real-time previews. Adds “Skip for now” on invites and guardrails to avoid incomplete team creation.
- **New Features**
- Added email invite pages for organizations and teams with shared EmailInviteForm and RoleSelector.
- Built a live invite browser preview that renders a 3×3 grid and updates as you type; works for orgs and teams.
- Applied route-keyed framer-motion transitions to layout, cards, and browser views for smoother page changes.
- Continuation prompt now detects saved org or team and routes to the right next step; localized copy.
- Added loading state to plan selection to prevent double navigation.
- Refreshed Organizations welcome modal with a new animated ring illustration and better scrolling.
- Added “Skip for now” to org and team invite-by-email steps to proceed without invites.
- Calendar browser preview now focuses on a time window around “now” for a more realistic demo.
- Added an optional floating footer to keep actions visible on long, scrollable lists.
- **Refactors and Fixes**
- Unified invite browser and replaced the org preview on the org email step.
- Split and simplified legacy invite views; team and org routes are cleaner and easier to extend.
- Streamlined the team invite step by removing a redundant action; non-admins are redirected to the email invite page.
- Prevented creating teams with empty details by redirecting back to team details.
- Minor UI cleanup: tighter borders, padding, and mobile max-heights across onboarding screens.
- Hide team select on org invites when no teams exist.
