Plan step 36, navigation review. The Tailwind-era rail-collapsed:
variant is now plain selectors in 26 rules, each repeated in five
window bands, across navigation-rail.css, navigation-rail-item.css,
navigation-rail-section.css and layout/scaffold.css; the tests pinned
a few of them. A new test walks every rule whose :where() names the
rail and fails when a copy drifts from the seven conditions for its
band, or when a rule is drawn collapsed in some bands but not all five.
ComponentStylesheet gains rules() for it.

Plan step 36. <x-loading> renders data-md-loading and data-md-contained,
and loading.css in material.components draws the 48px indicator in
primary, the contained circle and the still shape under reduced motion.
The view no longer reads the caller's classes to decide its size and
colour: a caller's utility outranks the package's layer on its own.
ActionStylesheetsTest checks the group's stylesheets for the package's
shape (layer statement, plain imports, material.components, tokens, px
breakpoints, imports of rendered components) and its views for class
lists; tests/Support/ComponentStylesheet reads a rule's declarations.
