An on-chain, shared to-do list realm for the gno.land **sapphire** testnet (gno 0.9).
Anyone can add an item to the board; each item records the caller's address as
its author, and can be toggled open/done or removed. `Render` shows the board as
Markdown checkboxes with live open/done counts, newest item first.

- **Realm path:** `gno.land/r/REPLACE_ADDR/todos` (replace `REPLACE_ADDR` with your deploy address)

## Exported transactions

| Function | Effect |
|---|---|
| `Add(text string) int` | Adds an item authored by the caller, returns its id |
| `Toggle(id int)` | Flips an item between open and done |
| `Remove(id int)` | Deletes an item |

All three are gno 0.9 crossing functions (`cur realm` first parameter) and must
be invoked with `cross(cur)` from another realm, or directly via `MsgCall`.

## Example calls

```sh
# Add an item (returns the new id)
gnokey maketx call -pkgpath "gno.land/r/REPLACE_ADDR/todos" \
  -func Add -args "buy milk" -gas-fee 1000000ugnot -gas-wanted 2000000 \
  -broadcast -chainid sapphire-1 -remote <rpc> mykey

# Mark item #3 done (toggle)
gnokey maketx call -pkgpath "gno.land/r/REPLACE_ADDR/todos" \
  -func Toggle -args 3 -gas-fee 1000000ugnot -gas-wanted 2000000 \
  -broadcast -chainid sapphire-1 -remote <rpc> mykey

# Remove item #3
gnokey maketx call -pkgpath "gno.land/r/REPLACE_ADDR/todos" \
  -func Remove -args 3 -gas-fee 1000000ugnot -gas-wanted 2000000 \
  -broadcast -chainid sapphire-1 -remote <rpc> mykey
```

## Example render output

```markdown
# Shared To-Do Board

2 open · 1 done · 3 total

- [ ] #3 walk dog (g1abc…)
- [x] #2 buy milk (g1abc…)
- [ ] #1 write realm (g1def…)
```
