Fact
Externally checkable scientific or historical claims supported by named sources.
Sources & Rights
Trust is part of the interface.
Claims, interpretations and media states stay distinguishable. This candidate uses official or institutional sources for factual foundations and original programmatic SVG diagrams for local visual explanation.
Editorial synthesis
ICU combines sourced ideas into an explanatory comparison; the synthesis itself is not attributed to a source.
Interpretation
Visual-character or representation commentary, presented as a lens rather than as meteorological fact.
Prototype / tool output
Observation Lab candidates are generated from disclosed rules and are not live diagnoses or forecasts.

Canonical description: “Atmospheric and moody.”
- Atmospheric → Field Atlas + Scale & Structure: the subject is organized around cloud layers, near-ground obscuration, precipitation columns, optical geometry and upper-atmosphere light.
- Moody → record-level mood metadata + restrained visual identity: “mood” remains editorial description, never a proxy for hazard, severity or forecast.
- Atmospheric and moody → Representation Gallery: the universe explicitly explores how haze, contrast, exposure, diagramming and artistic choices alter weather’s visual character.
- Nothing from the supplied description was excluded. Its brevity required careful expansion, but its two concrete promises are visible in architecture, data and design.
