Historical Era Visualization Cube

2x2 grid, do this for different years of vastly different eras: topic INPUT ::= [TOPIC], [ERA] STEP_1 :: infer era identity - time period or stage - dominant materials - key tools or artifacts - social/technical/cultural context - built environment or natural environment - representative agents or figures if relevant STEP_2 :: compress into cube - large objects define cuboid edges - medium objects build internal scenes - small objects fill gaps - top, side, and front faces remain visible - everything stays inside a strict rectangular volume STEP_3 :: create module text - large era label - short subtitle - compact bullet list - no fixed facts unless supplied STEP_4 :: repeat across eras - preserve identical visual grammar - increase or transform complexity chronologically
