Math is the loudest voice.

Twelve columns, one red dot, zero decoration. Drag the composition sliders and the poster re-typesets itself live — hierarchy is arithmetic you can play.

Raster

Every edge sits on the column math. Toggle 8/12/no-grid to audit the discipline — or break it.

Rot

Red is rationed. The red-ratio slider re-allots exactly that share of ink to the dot and rules.

Spannung

Tension slides blocks along the diagonal. High tension breaks margins; snap pulls them home.

Proof

Re-set deals a new hierarchy from the same parts. Nudge any block by clicking near it.

Exercise appendix · N — grid drill

Set it straight.

Three crooked posters. Tap the rule each one breaks — the drillmaster grades instantly and without mercy.

Poster 1: the red dot floats off-column. Which rule broke?

Grade 0 / 3 · the drillmaster watches

Raster

Every edge answers to the columns. Off-grid is not expression; it is litter.

Rot

One red, rationed. The dot is exclamation — a paragraph of red is shouting.

Spannung

Tension runs diagonal, never horizontal. Calm axes, wild diagonal.
