M3E applies the Material Design 3 typography system to encode visual hierarchy, editorial tone, and spatial rhythm across components. The system defines a 30-style type scale—comprising 15 baseline and 15 emphasized roles.

Typography tokens follow the prefix --md-sys-typescale-* for the standard typescale and --md-sys-typescale-emphasized-* for emphasized. Each typescale variant encodes font size, line height, weight, and tracking (or letter spacing)—for example, body-large is encoded using --md-sys-typescale-body-large-font-size, --md-sys-typescale-body-large-font-weight, --md-sys-typescale-body-large-line-height, and --md-sys-typescale-body-large-tracking.

M3E components support the full semantic range of the Material 3 type system, including standard and emphasized variants of: display-large, display-medium, display-small, headline-large, headline-medium, headline-small, title-large, title-medium, title-small, body-large, body-medium, body-small, label-large, label-medium, and label-small.

Each role is mapped to a tokenized style and applied contextually—for example, label-large for buttons, body-large for list items, and body-small for form-field hints.
