font_size_base = 13.0

Font size scaling

The font_size_base value determines all other font sizes used in the application:

• xs (extra small): base × 0.77
• sm (small): base × 0.85
• md (medium): base × 1.08
• lg (large): base × 1.23
• xl (extra large): base × 1.38

For example, with font_size_base = 13.0:

• xs ≈ 10px
• sm ≈ 11px
• md ≈ 14px
• lg ≈ 16px
• xl ≈ 18px
