Lucide · 1.75px stroke · 1rem. Outline icons with a consistent stroke width; size icons to match adjacent text and align them optically.
- Never use color as the only signal — pair it with text, an icon, or a shape.
- Every interactive element must be keyboard reachable and show a visible focus ring.
- Honor prefers-reduced-motion: reduce by disabling non-essential animation.
- Keep a logical heading order and give every form control a label.

The design brief
Horizon is a calm teal design system for SaaS marketing sites and product landing pages. Teal balances trust and freshness — credible enough for B2B, modern enough to convert.
Principles
- Teal as the single brand colour for CTAs, links, and accents.
- Balanced cool neutrals keep long landing pages readable.
- Clear hierarchy with one elevated card shadow for feature blocks.
When to use
Use Horizon for SaaS marketing, fintech, and developer-tool landing pages. Avoid it for loud consumer promos.
