A dice game realm for gno.land where every roll is verifiable. There is no true
randomness on-chain, so each roll's 1-6 face is derived **deterministically** from
public block entropy (the block height) mixed with the caller's address and their
running roll count. Anyone can recompute a roll from public data and confirm it was
never tampered with — that is what "provably fair" means here. The realm keeps a
per-caller roll history and a global distribution across the six faces.

- **Realm path:** `gno.land/r/REPLACE_ADDR/dice`
- **Network:** sapphire (gno 0.9)

## Example calls

```sh
# Roll the dice (state-changing crossing call, returns the 1-6 face)
gnokey maketx call -pkgpath "gno.land/r/REPLACE_ADDR/dice" \
  -func Roll -gas-fee 1000000ugnot -gas-wanted 2000000 -broadcast ...

# Query the current view (distribution chart + recent rolls)
gnokey query "vm/qrender" -data "gno.land/r/REPLACE_ADDR/dice:"

# Read one account's roll history (read-only helper)
gnokey query "vm/qeval" \
  -data 'gno.land/r/REPLACE_ADDR/dice.RollsOf("g1...")'
```

`Render(path)` output shows the total rolls, a `▓░` distribution bar chart for
faces 1-6 with percentages, and the most recent rolls.
