The grid-square map drew the world two or three times across a wide window, each
copy carrying the same squares — worldCopyJump earns its keep on the great-circle
map, where a path reads better crossing a second Asia, and costs only confusion
on a map of where you have been heard. It is off here, the tiles no longer wrap,
and addBasemap takes the option so the other map is untouched.
Zooming out far enough to hold Greenland and Antarctica together was impossible:
the floor was zoom 1, and one step further out was already too far. Zoom 0 is
the whole planet, and the view now opens on a fitWorld computed from the
container rather than a guessed zoom level — repeated once when the container
first has a real size, because the tab is mounted hidden.
That exposed the next thing: Esri answers a request outside the world with a grey
"Map data not yet available" tile, and zoomed out that was most of the screen.
The tile layers carry a bounds, so those tiles are never asked for, and what is
left beside the planet is the panel's own background instead of a white slab.
Finally the mode filter offers All, Phone and CW beside Digital and FTx. The
backend already accepted all of them — GridSquares understands "ALL" and the
ModeClass names — only the interface was offering two.
