Plan step 36 follow-up. Deleting navigation.css also deleted the only
definition of the rail-collapsed: custom variant, which
scaffold.blade.php's data-app-shell-actions row still uses
(rail-collapsed:flex-col) — scaffold's own rewrite is a later batch, so
it is still Tailwind. Left alone, that class would silently stop
matching anything. The definition moves into tailwind.css, updated to
the data-md-* hooks navigation-rail.css now renders (data-rail and
data-rail-auto are unchanged, so those branches needed nothing);
otherwise it reproduces the same seven branches navigation-rail.css's
own header documents, so the two cannot drift silently in what
"collapsed" means. It goes with the scaffold's own rewrite.
theme-script.blade.php's doc comment, which named the old variant, now
points at navigation-rail.css directly.
