Lucide · 1.5px 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
Bone is a warm off-white minimal design system. Bone-coloured paper with stone-black ink gives a calm, content-first surface that feels softer than stark white-on-black.
Principles
- Warm neutrals over pure white reduce glare and feel human.
- One near-black primary; the rest is greyscale rhythm.
- Restraint everywhere — type and spacing carry the design.
When to use
Use Bone for reading apps, calm SaaS, and content tools that want warmth without colour. Avoid it where a bold brand hue is required.
