Typography scale

Theme settings → Typography picks heading and body font families. Character (Refined vs Bold) adjusts weight and presence without replacing your font choices.

Fonts

• Heading font — used for section titles, product titles, and display type
• Body font — used for paragraphs, forms, and most UI labels
• Shopify font picker loads licensed fonts for the storefront; system fallbacks apply while fonts load

Scale and hierarchy

• The theme uses a consistent type scale (display → h1–h3 → body → caption).
• Section settings rarely override base sizes — prefer Theme settings for storewide changes.
• Bold Character increases heading weight; Refined keeps softer weight and shadow.

Accessibility

• Keep body text at least the theme default size for mobile readability.
• Avoid ultra-light weights for body copy on dark backgrounds.
• Do not rely on italic alone to convey meaning.

How to check it worked

1. Change heading font and save — homepage hero and product titles should update.
2. Change body font — descriptions and buttons labels should match.
3. Toggle Character — heading weight and card shadow should shift without changing the font family.
