rega's 3c3bde71 fixed a real defect: ShareButton is the map toolbar's 40px round
control plus a 2px ring, so it measured 44px inside a 38px bar and overflowed it. At
28px + ring it matches the search box, which is what the Driver asked for.
The side effect is that the TAP TARGET went to 32px, and this repo states its own floor
twice -- DataTable.vue:294, "44px is the accessible tap target; anything smaller is a
miss on a phone", and LegendDesktop.vue:124 sizes rows to keep it. Nothing in the change
said otherwise; the target simply followed the drawing, which is what tap targets do
unless someone stops them.
A transparent box centred on the button restores it without moving a pixel: absolutely
positioned so it changes no layout, and part of the button so it takes the same clicks.
The visual stays exactly as the Driver approved.
44 WIDE, 38 TALL, AND THE 6px IS DELIBERATE. The bar is 38px, so a 44px-tall target
would hang 3px over the filters row and start taking taps meant for a filter -- one miss
traded for another. 44x38 is the largest target that costs nothing else. Closing the
last 6px needs a taller bar, and the Driver has just decided that axis in the other
direction, so it is asked rather than assumed.
