What this shows
Each round-table-8 draws its 8 chairs on the circumference (60″ top per banquet-industry convention), so 15 tables = 120 covers, countable in the SVG. The two grids and one row place all fifteen tables in three statements.
The collision validator checks chair-ring envelopes, not table discs — squeeze the grid area by a meter and it names the exact pair of tables that now conflict and by how much. The head table seats one side only, facing the room.
