A "king of the hill" dice game for gno.land (sapphire / gno 0.9). Call `Roll()`
to throw a deterministic 1-100 die; beat the reigning king's roll and you
dethrone them, becoming king yourself. Unlike a typical leaderboard that just
sums points, this one ranks players by **accumulated reign length in blocks**
— a single lucky high roll only pays off for as long as nobody beats it, so
outlasting the field matters more than the roll itself.

**Realm path:** `gno.land/r/g12cs4cehujpffpjpywmkqj43m6u5ya53nj69sjz/kingofdice`

## Public API

| Function | Kind | Description |
| --- | --- | --- |
| `Roll(cur realm)` | crossing (tx) | Roll 1-100; dethrones the king on a higher roll. |
| `Render(path string) string` | view | Current king + reign-length leaderboard. |

or query it:

```sh
gnokey query "vm/qrender" -data "gno.land/r/g12cs4cehujpffpjpywmkqj43m6u5ya53nj69sjz/kingofdice:" -remote <rpc>
```

## Toolchain status

Verified locally: `gno test .` passes (built against a `gnolang/gno` checkout
as `GNOROOT`, since the machine's configured `GNOROOT` pointed at a stale,
deleted path). Tests avoid `gno.land/p/nt/uassert/v0` — the cached copy of
that package uses the bare `cross` builtin as a function value, which the
locally installed `gno` (master) rejects; plain `testing.T` calls sidestep
that unrelated cache/toolchain drift.
