Plate III — Repetition

Structural intent

Show modular recurrence: the same structural unit repeating in a stable rhythm. The key property is repeatability under a shared rule.

What must be observable

• A repeating unit (column, tile, beam, step, panel, arch) present at least 5–7 times.
• Regular spacing (or a consistent progression) that indicates a governing pattern.
• Perspective that preserves the rhythm (no chaotic occlusion).
• Continuity of the repeated element’s geometry.

Common failure modes

• Variety mistaken for repetition (units change shape/scale unpredictably).
• Repetition diluted by one dominant focal object that overrides the rhythm.
• Too few instances to establish a rule (only 2–3 repeats).
• Repetition present but camera angle breaks the pattern’s legibility.

UI / system translation (non-symbolic)

• Use for lists, catalogs, grids, and any “many items” interface.
• In UI: consistent card dimensions, spacing tokens, and predictable hierarchy.
• In system terms: define a component spec once; render many with uniform props.
• QA: require minimum repeat count and consistent unit geometry.
