First line: a bordered text field with optional leading icon and trailing keyboard hint.

```jsx
<Input placeholder="Поиск по проектам…" icon="Search" />
<Input placeholder="Поиск" icon="Search" kbd="⌘K" size="sm" />
<Input as="textarea" rows={3} placeholder="Опишите задачу для агента…" />
<Input type="email" placeholder="you@company.ru" icon="Mail" />
```

Notes
- Border lights to `--ring` with a soft `--shadow-focus` glow on focus-within.
- Pass `kbd` to surface a shortcut chip (search fields); `icon` is muted until focus.
- For the chat/agent composer, compose this with the `Button` send control rather than reaching for a one-off.
