Usage

  1. Lead with the primary.

    It belongs on calls-to-action and one accent moment per screen. Not on body copy.

  2. Two type families, three weights.

    Display for headlines, body for paragraphs. Resist a third unless there is a real reason.

  3. Snap to the spacing scale.

    Padding, margin, and gap should land on the values in §05. One-off pixels accumulate into noise.

  4. Treat accessibility as a hard constraint.

    When a colour pair fails WCAG, fix the colour — not the contrast check.
