360 panoramas
A 360 panorama usually starts as a flat 2:1 image. The viewer wraps that image around you, so dragging the view feels like standing inside the scene instead of looking at a normal wide photo.
The page starts with a poster, then loads the heavier 360 viewer when it is useful. That keeps browsing light while still making room for fullscreen, drag controls, and higher-detail sphere images.

Why the variants exist
Browsers, screens, networks, and media types do not agree on one perfect file. The page stays simple, while the saved asset details keep source kind, quality level, preview confidence, dimensions, format, and fallback intent.
Each asset gets the special handling it needs. The goal is not to show off file formats; it is to make the page choose the right thing quietly, then explain the machinery only when you ask.
