An on-chain score leaderboard realm for gno.land (sapphire / gno 0.9). Any account
can accumulate points with `AddPoints(n)` and optionally attach a display name
with `SetName(name)`. `Render` returns a Markdown table ranked by points
descending — gold/silver/bronze medals for the top three — plus the total player
count. State is kept in an `avl.Tree` so rendering is deterministic across nodes.

**Realm path:** `gno.land/r/REPLACE_ADDR/leaderboard`

## Public API

| Function | Kind | Description |
| --- | --- | --- |
| `AddPoints(cur realm, n int)` | crossing (tx) | Add `n` (> 0) points to the caller's total. |
| `SetName(cur realm, name string)` | crossing (tx) | Set the caller's display name (≤ 32 bytes; empty clears it). |
| `Render(path string) string` | view | Ranked Markdown leaderboard. |

## Example calls

```sh
# Add 10 points to your total
gnokey maketx call \
  -pkgpath "gno.land/r/REPLACE_ADDR/leaderboard" \
  -func AddPoints -args 10 \
  -gas-fee 1000000ugnot -gas-wanted 2000000 \
  -broadcast -chainid sapphire-1 -remote <rpc> <keyname>

# Set your display name
gnokey maketx call \
  -pkgpath "gno.land/r/REPLACE_ADDR/leaderboard" \
  -func SetName -args "Alice" \
  -gas-fee 1000000ugnot -gas-wanted 2000000 \
  -broadcast -chainid sapphire-1 -remote <rpc> <keyname>
```

View the rendered leaderboard in gnoweb at
`/r/REPLACE_ADDR/leaderboard`, or query it:

```sh
gnokey query "vm/qrender" -data "gno.land/r/REPLACE_ADDR/leaderboard:" -remote <rpc>
```
