Core snippet

// Load the underwood module.
const plot = new GysinPlot({ seed: 1961 });
plot.underwood("KICK THAT HABIT MAN", 60, 90);   // period typewriter, defaults
plot.draw();

// Emphasis stays mechanical: second strike, rule, capitals, spacing.
plot.underwood("HEADING", 60, 90, { size: 24, underline: 1 });
plot.underwood("DOUBLE-STRUCK", 60, 130, { bold: true });
plot.underwood("* * * * * * * *", 60, 170);   // a divider it could type
plot.underwood("the small voice.", 60, 210);  // both cases, one face

// wear scales strike irregularity from one knob (0 = clean).
plot.underwood("KICK THAT HABIT MAN", 60, 210, { wear: 0 });

Sperrsatz

One face, one size. Emphasis comes from a second strike, an underscore rule, capitals or S p e r r s a t z: letters spaced across the line.
