Season ≠ weather event
Axial tilt sets the annual seasonal geometry. It does not guarantee snow, ice, a particular temperature, or a specific storm.

Winter
A field-and-explanation universe for reading winter across scale: orbital geometry, daylight, snow and ice, atmospheric phase changes, regional processes, and the choices people make when representing them.
Scope boundary: Winter is a season, not a synonym for snow. Local conditions vary by hemisphere, latitude, elevation, water, circulation and weather. This universe does not infer your location or current conditions.
Orientation
Start with three boundaries.
Appearance ≠ diagnosis
A bright white surface, feathery ice, or falling pellets can suggest hypotheses. Identifying a process responsibly still needs context and evidence.
Representation ≠ source
Winter diagrams on this site are explanatory constructions. They are not documentary photographs and are labeled accordingly.

Flagship system
Constraint Lab: change the premises, not the facts.
Five constraints. One evidence boundary.
Vary hemisphere, latitude band, surface state, moisture, and a simplified vertical temperature profile. The lab responds with interpretations that remain defensible under those constraints and explicitly states what it still cannot know.
Canonical source boundary
The source record had no description.
Preserved source material: ID VIS-0194, exact title Winter, collection/section, theme tags, format tags, and rights-review flag.
Newly authored elaboration: every explanatory thesis, taxonomy, route, interaction and scientific synthesis in this universe. ICU does not imply that a missing source synopsis existed.
