<bmx-avatar-group>
The overlapping stack of faces that says who is on something.
max="4" over five people draws all five: a counter reading +1 takes the same room as the
face it replaced and tells the reader less. Over six it draws four and a +2. The rule is shared with
bmx-chip-set, because it is arithmetic rather than a property of either.
+2 is drawn and never read; what it announces is “2 more: Priya Raman, Tom Baird”.
The faces themselves are decorative and the group carries the name — eight avatars each
announcing themselves is eight announcements to sit through before reaching the rest of the row. The overlap is a
logical margin, so the stack leans the way the reader reads and mirrors in Arabic and Hebrew with no second rule.
