Top bar: every document command is an icon button in a run — panes, new/open,
undo/history/redo, cut/copy/paste/duplicate, snapshots — with the title and
status in the middle and export, share and account on the right. Pane toggles
are pictures of the window with that pane filled in.
Stage bar: tracing, onion and passepartout are all the same toggle-plus-settings
split button, followed by one zoom group, with fit inside it.
Popovers: one `menu/popover`, measured against its button and dismissed by a
scrim, replaces the <details> popouts that never closed on an outside click.
Palette: the strip ends in a palette button whose popover lists every palette
with its swatch strip, renames the open one in place, and marks the ones on
the stage. An info badge says when the palette being edited is not one the
stage draws in at the playhead; both ends of a palette-lane blend count.
`clip/palette-at` is the resolver's root palette lookup, pulled out so the
strip asks the same question the renderer answers.
