A photograph is rarely the shape of the slot it goes in, so something decides which part survives. It
was a centred crop and no way to change it.
Dragging the picture slides the window; the wheel zooms, anchored to the pointer so the thing under the
cursor stays under it. Both write the site's own format — `x,y,w,h` in percentages of the ORIGINAL —
which is resolution-independent and survives the file being re-encoded.
Zooming in is the window getting smaller: w and h shrink together, keeping the slot's shape. Fit is the
floor, because you cannot show more of a photograph than there is, and at exactly fit the crop is
cleared rather than written as the centred value — a null crop and a crop that happens to be centred
should not be two states.
── The preview is not object-cover ──
It draws the rectangle: the picture scaled to `100/w` of the box and offset so the chosen corner lands
at the origin. object-cover shows the largest window of the slot's shape that fits and nothing else —
it can be panned and it cannot be zoomed, so a preview built on it would silently ignore half of what
this control produces.
── Also here ──
buildSite now hands the site an av-club URL and user. That is the first piece of publishing images
cropped rather than cropping them in the browser with CSS: the plugin knows the sidecar registry, the
site knows a URL. Inert until the site uses it.
