/* ========================================================================== site/paper.css · THE PAPER LADDER — the site's selection system ========================================================================== Chosen from ten directions on 2026-09-09 (option 08, /doctor/selection- states-x6.html). One rule, applied everywhere: A SELECTION ROW SITS ON A GROUND ONE STEP DARKER THAN THE PAGE. THE CHOSEN CONTROL IS THE ONLY WHITE PAPER IN THAT ROW. Nothing else marks a selection — no navy fill, no accent, no shadow, no inlay bar. Depth is ground tone and nothing but ground tone, so a second and third level can nest inside the first without inventing a new mark: the ladder just steps down again. level 1 row #EDF2F9 chosen #FFFFFF (every group on the site) level 2 row #F4F7FC chosen #FFFFFF (a row inside a chosen panel) level 3 row #F6F8FC chosen #FFFFFF (a row inside that) The site has no second level today — verified on all six live pages: none of the sixteen selection groups sits inside another. Levels 2 and 3 are declared below so the ladder exists the moment one is added. THE SHAPE FOLLOWS WHAT THE GROUP IS, not what level it is: · a DOCK — its panel is directly beneath, so the chosen control takes top-only radius and its white runs straight into the panel · a TRACK — a filter whose content is further away, so the chosen control is a fully rounded plate inside the row · a RAIL — vertical; the same weld turned a quarter turn, the chosen row's white running sideways into the panel beside it --------------------------------------------------------------------------- HOW IT WINS --------------------------------------------------------------------------- Linked LAST in every page's — after ds.css / shelf.css / uifinish.css / hier.css / panel.css and after each page's own late
