## LineChart
Line chart for trends over an ordered category axis. One path
per series on the design-token palette; zero-dependency SVG, responsive,
dark-mode aware, with optional points, gridlines, legend, and a screen-
reader data-table fallback.

**Import:** `import { LineChart } from '@urbicon-ui/blocks';`

### Examples
```svelte
<LineChart
  data={[
    { label: 'Mon', values: [12] },
    { label: 'Tue', values: [18] },
    { label: 'Wed', values: [9] }
  ]}
/>
```
