- flex-shrink: a line whose children want more room than it has takes it back from those that
shrink, in proportion to shrink times size and never below a min size, a fixed size or the
content. A scroll box shrinks (and scrolls), and a box in a column shrinks as far as the scroll
boxes inside it let it, so a list in a column takes the room its siblings leave with no height.
`flex: grow shrink`, and `flex-shrink` by name.
- A row wider than its room measures its texts (and boxes without a width) again in the room the
rest leave them, so a line wraps beside an icon.
- calc() with + - * / and brackets over px, %, em, rem, vw, vh, plain numbers and var(); a width
or height keeps its percentage, taken of the room it is given. Lengths lists (padding, margin)
keep a calc()'s spaces.
- `order` places a box's children without touching the tree.
- width: 0 and height: 0 are 0: an unset size is UI_AUTO now, not 0.
- A component root that is itself a component takes each user's class, style and id in turn (the
outermost's id wins), and the rules of all their sheets are weighed by specificity together; a
user's rule wins a tie. The parent's sheet used to override the child's whatever its specificity,
and a middle component's sheet was lost.
- The default sheet lays .ui-track out as a row, so a range's fill is as tall as its track and a
checked box's knob goes right; a range's thumb is centred on the fill's end.
- ui_boxes.ludic.
