🐰✨ Keys in rows, oh what delight!
Grid-aligned and oh-so-right,
From one long line to many neat,
Organization, fresh and sweet!
A tidy press, a cleaner sight. 🎹

In `@src/components/Trackpad/ExtraKeys.tsx`:
- Around line 27-33: The button in the ExtraKeys component is missing an
explicit type which can cause accidental form submissions; update the JSX button
element inside the ExtraKeys render (the <button ... onPointerDown={e =>
press(e, k)}>) to include type="button" so each key button does not act as a
submit button; locate the button that uses the key variable k and the press
handler and add the type attribute.
- Around line 24-26: The row mapping uses the array index as a React key which
can cause state/order glitches; update the JSX mapping over ROWS in
ExtraKeys.tsx to use a stable unique identifier instead of the index (e.g., a
precomputed id on each row object or a deterministic string from the row
contents) so replace key={i} with something like key={row.id} or
key={row.map(k=>k.label).join('-')} while preserving the existing ROWS constant
and the inner row.map(k => ...) rendering.

⚠️ Potential issue | 🟡 Minor

Use a stable key for rows (avoid array index).
Line 25 uses the array index as a key, which can cause state glitches if rows ever reorder.

✅ Suggested fix

-      {ROWS.map((row, i) => (
-        <div key={i} className="flex gap-2 justify-center">
+      {ROWS.map(row => (
+        <div key={row.join("|")} className="flex gap-2 justify-center">

[error] 25-25: Avoid using the index of an array as key property in an element.

This is the source of the key value.

The order of the items may change, and this also affects performances and component state.

Add explicit button type to avoid accidental form submits.

[error] 27-33: Provide an explicit type prop for the button element.

The default type of a button is submit, which causes the submission of a form when placed inside a form element. This is likely not the behaviour that you want inside a React application.
Allowed button types are: submit, button or reset
