pub const H0: f32 = 50.0;Expand description
Frozen px sizes for the typographic scale, largest (H0, a display
heading) to smallest (BODY_XS, fine print). H0…H3 are the heading
ramp; BODY is running text, with BODY_S / BODY_XS for secondary and
caption text. Each is the px size; for sizes that scale with the surface
use the responsive h0…body_xs functions instead.
