One SVG figure re-equipped across three model-chosen periods of human history. The slider exposes whether it is a real rig, while the labels and weapons test historical accuracy and the model's choices reveal what it knows beyond the default Western examples.
Review the final period first, then drag slowly across the full range. Compare detail and finish across all three periods; different equipment may be simpler, but no period should be a placeholder.
Rig and motion. Watch the feet, shoulders, and head at every boundary. A valid solution keeps one body fixed and changes attached layers. Cross-fading separate figures causes drift, rescaling, or a visible change of pose. Inspect the SVG if the motion is ambiguous.
Repeatability. Move away from a period and back. The result must be identical. Check for Math.random, time-based values, and state that accumulates as the slider moves.
Historical choices. The periods must be chronological, at least a century apart, and specific about date and place. Their range is part of the result: reward well-supported choices outside the usual European-medieval-to-modern path, but do not reward novelty over accuracy.
Drawing against label. Check the equipment name, materials, and weapon against what is visible. A correct label with the wrong silhouette, construction, or weapon is not a correct period.
The timeline note. The stated non-specialist detail should be concrete and checkable, not a generic fact about armour.
Honesty. The final section should identify a real uncertainty or a legibility trade-off. A specific admission is stronger than a vague disclaimer.
Ranking: a stable shared rig, three accurate and equally finished periods, matching labels, and an honest limitation > a stable rig with a disclosed weak period > three separate illustrations honestly presented as such > separate illustrations claimed to be one rig. Visual polish breaks ties only after those checks.
Build one self-contained HTML page for a museum armoury exhibit: a standing figure and a slider that re-equips that same figure across three periods of human history.
Choose any three periods from recorded human history, anywhere in the world. Put them in chronological order and keep adjacent choices at least 100 years apart. For each, name a specific year and place; if an exact year is impossible, give the tightest defensible date range and explain it in the label.
Choose periods you can depict accurately. You are judged on the drawing as well as the interface.
Math.random, clocks, or accumulated state.localStorage, , cookies, or .sessionStorageindexedDBOne line per period: date, place, equipment, weapon, and one specific detail a non-specialist might miss.
One paragraph explaining the attachment points, layer order, and interpolation between periods.
One fenced html block containing the complete page.
Name the least certain historical choice and any accuracy compromise you made for legibility.
I will move the slider slowly in both directions, watch the feet and shoulders for drift, compare labels to drawings, inspect the SVG structure, and go straight to the final period before judging the rest.
