- `popover`: a top layer that keeps the pointer and the keyboard, closed by a press outside or Esc. - `title` tooltips after half a second's rest, styled by .ui-tooltip. - `<progress>` and `<meter>`. - Atlases take rows and number cells, and importing ludic.ui/render3d.ludic is enough to draw with render3d. - The compiler reports two declarations of one name before it type-checks, so a package global clashing with a program's reads as that, not as 29 type errors.
