TT Fors at the 600 ceiling — nothing on the page is bolder. Level 1 steps 36 → 44
→ 48 at the reference's breakpoints; the tracking **relaxes** to −0.01em at the
narrow width (measured — copy the direction). Line-height 1.2 everywhere.

```tsx
<Heading level={1}>Get AI visibility data you can act on</Heading>
