LIT Step 250 is 750. The page then counts by steps of 1 through step 1000, which is 0. That is 751 overlays. Together with the 250 on the first page, the scale holds 1001, one element on every step from 1000 down to 0. The first chip is +P. The fold continues at the next slot, an 8, and the slot after that is the reverse 8. The short row of 3 on the first page stays short. A failed count throws.
AMBER The 118 symbols and names are the arrays in Downloads\Periodic-Table-Phd.html, read on 2026-10-01. The numbered copy was not used. The elements continue after +Si. The fold cursor continues. It does not go back and lengthen the short row. The order is assigned. This page is not one of those 144.
WALL This page does not publish the periodic-table application. A matching symbol is not a measurement of air, and the countdown is not a claim about weather, physics, or authority. The last row takes 1 of a 2 and does not finish that slot. Step 1001 is not drawn here. The wrap from 0 back to 1000 is the first page. The walk was already full, so this page is not seated.
