a894bdd deleted .action-menu-item/-label/-icon/-check/-description and the
.sheet-list-icon/-check/-description rules as unused, but ActionMenu builds
those names as `${base}-item` (base 'action-menu' or 'sheet-list'), which the
dead-class scan did not recognise. Every ⋯ dropdown and its bottom-sheet form
lost their row layout, hover, danger colour and check mark. Both files are
restored to their state before that commit.
The class-usage test now covers every stylesheet (not only media) and
understands built names: `${expr}-suffix` with a literal prefix, and
`prefix-${expr}`. Library markup (Notyf, DPlayer) is exempt.
