Icons

Font Awesome (Pro 6) is the default icon set. Guidance (proposed defaults):

• Use the solid style for primary UI; regular/duotone sparingly and consistently.
• Size icons to match adjacent text (≈1em); keep sizes uniform within a group.
• Let icons inherit text colour; use a brand colour only to signal meaning (e.g. red = destructive/alert).
• Keep clear space around icons; don't crowd them against text.

Consistent style & size    Mixing styles/sizes or decorative overuse
