## Background
```css
:root { --color-bg: #faf6ee; --color-surface: #f2ebdd; --color-text: #2a2620; }
```
- Use a warm ivory background (#faf6ee).
- Do not use cold white, gray or dark backgrounds.
## Buttons
- Use exactly one filled button per task area, for the main action. Make secondary actions text links. Do not repeat the same action (e.g. Save) in two places.
- Do not use two or more filled buttons in the same task area.
## Tone
- Write polite, explanatory copy. Use concise verb phrases that explain the next action (e.g. Start for free).
