A classic Magic 8-Ball as a gno.land realm. Ask a yes/no question and the current
**block height** picks one of the 20 canonical answers — fully deterministic, since
there is no true randomness on-chain.

- `Ask(cur realm, question string) string` — records `{caller, question, answer, height}`
  and returns the answer (crossing function; emits a `Shaken` event).
- `Asked() int` — how many questions have been asked (read-only).
- `Render(path string) string` — shows the last answer and a table of recent shakes.

Built for the sapphire testnet (gno `0.9`). Example:

```
gnokey maketx call -pkgpath gno.land/r/moul/x/daily/eightball/v0 \
  -func Ask -args "will this PR pass CI?" ...
```

## What changed in v1

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

**One address format.** Eleven realms carried their own `shortAddr` with four different truncation rules, so the same account rendered differently depending on which realm you opened. `ui.Addr` is that decision made once: 8 leading characters, an ellipsis, 4 trailing, in backticks.

Visible change: addresses now render in monospace.

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.
