* Responsive league row layout and mobile polish

- League rows stack avatar+name on top, stats full-width below on mobile
- Stats spread to right side on sm+ screens with border separator on mobile
- Tighter padding on mobile (px-3/py-3), full padding on sm+
- Card headers and content use px-3 sm:px-6 to reduce mobile gutters
- Two-column home layout deferred to lg breakpoint (tablet gets stacked)
- Active leagues sorted by completion percentage descending
- Default rank 1 / 0 points for active leagues with no scoring events yet
- Fix ordinal bug for 11th/12th/13th; add aria-labels to rank change indicators
- Remove dead StatDivider className prop

* Improve claude file.

* Add StandingsPreview card component with podium row styling

- New StandingsPreview component with gold/silver/bronze row tints for
  top 3, team avatar, and LeagueRow-style stat columns (Ranking + Points)
  with rank and 7-day point change indicators
- Fix GradientIcon in Storybook by adding BracktGradients decorator to
  preview.tsx (renamed from .ts to support JSX)
- Fix degenerate SVG gradient on horizontal strokes by switching
  BracktGradients to gradientUnits="userSpaceOnUse" with Lucide-space
  coordinates (0→24)
- Revert erroneous fill: url(#gradient) from GradientIcon; stroke-only
  fix was sufficient once gradientUnits was corrected

# Architecture
## Server
Dual-server setup:
- **server.ts** — HTTP server entry point, initializes Socket.IO
- **server/app.ts** — Express app with React Router SSR handler and database context
- **server/socket.ts** — Socket.IO server for real-time draft updates
- **server/timer.ts** — Runs every second via `setInterval` to advance draft timers. Uses a dedicated DB connection. **Must be started** for draft functionality to work.
## Database Layer
- **Schema**: `database/schema.ts`
- **Context**: `database/context.ts` — DB connection injected via `AsyncLocalStorage`
- **Models**: `app/models/` — all DB queries live here, organized by domain (e.g. `league.ts`, `season.ts`, `draft-pick.ts`)
Always query through the model layer — never write Drizzle queries directly in route files.
## Frontend
- **Routes config**: `app/routes.ts` — all routes must be explicitly registered here (React Router 7 does not auto-discover files)
- **Route files**: `app/routes/` — file naming uses `.` as path separator; `$param` for dynamic segments; `_index.tsx` for index routes
- **Components**: `app/components/` — UI primitives in `app/components/ui/` (ShadCN)
- **Hooks**: `app/hooks/` — custom React hooks
- **Lib**: `app/lib/` — pure utility functions
## Real-time (Socket.IO)
Clients join a room per season. Key events:
| Event | Direction | Trigger |
|---|---|---|
| `join-draft` | client → server | on draft page load |
| `timer-update` | server → client | every second during active draft |
| `pick-made` | server → client | participant drafted |
| `autodraft-updated` | server → client | team enables/disables autodraft |
| `team-connected` / `team-disconnected` | server → client | presence |
Server emits via `getSocketIO()` from `server/socket.ts`. Clients consume via `useDraftSocket()` hook at `app/hooks/useDraftSocket.ts`.
### Adding a Socket Event
1. Define types in `server/socket.d.ts`
2. Add handler in `server/socket.ts`
3. Emit from server: `getSocketIO().to(room).emit(...)`
4. Listen in client component or hook
