Best-of-three rock-paper-scissors against the house, played across multiple
calls instead of a single stateless throw. Each `Throw` plays one round of
your current match (starting a new one if you don't have one in progress);
the house's move is derived deterministically from the current block height,
a per-realm nonce, and your address. First to two round wins takes the
match, and every player's match record (wins, losses, rounds played) is
kept on-chain and viewable per-address.

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

## Example calls

```sh
# Play one round of your current (or a new) match
gnokey maketx call \
  -pkgpath "gno.land/r/g12cs4cehujpffpjpywmkqj43m6u5ya53nj69sjz/rpsmatch" \
  -func Throw -args "rock" \
  -gas-fee 1000000ugnot -gas-wanted 2000000 -broadcast -chainid sapphire-1 <key>

# View the arena dashboard
gnokey query vm/qrender \
  --data "gno.land/r/g12cs4cehujpffpjpywmkqj43m6u5ya53nj69sjz/rpsmatch:"

# View one player's record
gnokey query vm/qrender \
  --data "gno.land/r/g12cs4cehujpffpjpywmkqj43m6u5ya53nj69sjz/rpsmatch:g1youraddress..."
```

## Toolchain

Written against the sapphire (gno 0.9) stdlib split (`chain`, `chain/runtime`,
`gno.land/p/nt/avl/v0`). The `gno` binary on `PATH` here is a newer/older
mismatch of its own `GNOROOT` (native-function drift), so tests were run
against a `gno` built from the exact pseudo-version pinned in that binary's
own module info (`github.com/gnolang/gno@v0.0.0-20260605043206-bf5b31eda8b9`).
All 5 tests pass (`gno test -v .`) and `gno lint .` is clean.

## What changed in v1

Identical behaviour to [`v0`](https://github.com/moul/gno-contracts/tree/4f2df83869b80470eb81c48a82fdbe82256b8113/r/moul/x/daily/rpsmatch) apart from rendering, which now goes
through [`p/moul/kit/ui`](/p/moul/kit/ui/v0) instead of the local `escapeInline` helper.

**Real escaping.** The local helper replaced a handful of markdown metacharacters. `ui.Inline` and `ui.Cell` delegate to [`p/nt/markdown/sanitize`](/p/nt/markdown/sanitize/v0), which also strips bidi and zero-width characters and folds newlines, so user text cannot reorder or escape the line it sits on.

The rendering change means the output differs from v0, which under this repo's versioning rule is a compatibility change, hence a new version rather than an edit in place. `v0` stays live and untouched.
