+**The Monitor board is declared, not laid out.** `include/monitor_board.php` holds one array
+naming every card on the Monitor grid, its width and its order, and generates the whole layout
+from it — the column ladder, the span clamps at each width, the row-height cap, and the
+compensation when a conditional card is absent. Column counts are 8/4/2/1 and spans are 1/2/4/8,
+which is what lets the board re-cut itself at any width with no holes and no hand-placed card.
+Breakpoints are arithmetic over `VV_MON_CARD_FLOOR`, never chosen by eye. `pages/monitor.php`
+carries the card bodies and nothing about where they go; moving a card is moving a line in that
+array. The page cross-checks the declaration against the cards that actually rendered and says so
+in the browser if they disagree.
 
 **Caching.** Several endpoints serve from `$VV_CACHE_DIR` (`/tmp/varaverk/api`, tmpfs) rather than hitting live
 APIs on every page view, refreshed by `Tools/api_cache_writer.sh`. `?live=1` bypasses the
