Shape

Five corner radii, each for one kind of thing, and one signature: the docked panel that grows out of the page header's line.

Corners

The top-left corner at three times its size for each of five radii: 6, 8, 12, 14 and 18, with the name and use of each. — The five corners, at three times.

Name	Pixels	For
`art`	6	Small art up to 32, key caps
`row`	8	Rows, washes, art up to 72
`slab`	12	Slab, fields, large art, a ring around a picture
`panel`	14	Docked panels, groups
`window`	18	The window

A ring around something at an inset takes its corner plus the inset. A picture with corner 8 and a ring 4 outside it has a ring of 12. The keyboard ring is 2 outside the item, so a row, corner 8, has a ring of corner 12.

The tokens also hold rowSlab (10). No part of the kit uses it.

Docked coves

A panel grows from a line. The docked panel hangs from the page header's hairline into the window's right edge as one shape with them. Where its top edge meets the line there is a cove, a concave curve of 10 that joins them (the fillet). Its one free corner, at the bottom left, is 14. It is not a card laid on the page.

A page header and a docked panel at one and a half times their size, the panel hung from the header's line, with markers on the cove at its top-left and on its bottom-left corner. — The panel and the line, at 1.5 times.

CoveA concave curve of 10 where the panel's top edge meets the hairline.
CornerThe panel's one free corner, 14.

DockedPanel fixes the cove at 10. Only Docked, the shape under it, takes a fillet of its own (6 unless set) and a cornerRadius for the free corner (17 unless set). See the docked panel. ## Where not to round {#flat}

A run of selected rows is one wash, round only at its ends (see States). The hairline is square. A window is round only where it is a window: a crop in a figure runs off its edges, so that it never shows four corners like a floating card.
