Getting Started

2. Clone your fork:

   git clone https://github.com/<your-username>/Joint_Save.git

Overview

During initial data load, the UI shows empty states or nothing. Skeleton loaders improve perceived performance across the dashboard and group detail pages.

Requirements

Dashboard (my-groups.tsx)

• Replace empty render during loading with skeleton pool cards matching real card dimensions
• Use existing <Skeleton> component from components/ui/skeleton.tsx

Group Detail (group-details.tsx, group-members.tsx, group-actions.tsx)

• Skeletons for: pool name, balance, member list rows, action buttons
• Resolve per-component as each data source returns (not all-or-nothing)

Profile (profile.tsx)

• Skeletons for stat numbers while fetching

Acceptance Criteria

• Skeletons visible during initial load on all three pages
• No layout shift when real data replaces skeletons
• Uses existing <Skeleton> component only (no new dependencies)
• Works on mobile viewport
