Bulk Bar

Every string the bar renders or announces.

The bulk actions, in inline priority order. An action with `options` is a picker; one without is a command.

The selection the bar acts on, as a snapshot (`tableSelection`, `idSelection`, …). The bar opens while it has rows.

The page's color mode. `surface="inverse"` takes the other one; the bar's popups take this one.

The count chip's color. neutral: one surface step down (`surface.ground`). highlight: the selection color the selected rows wear.

The bar's color mode. page: the page's own mode. inverse: the opposite mode, scoped to the bar (needs `colorMode`); its popups go back to the page's.

Where the bar floats. container: bottom centre of the nearest positioned ancestor (the pane). viewport: fixed to the bottom of the window.

How many labelled actions fit inline; the rest move into "More". The framework measures and passes it (`fitInline`). Omit for all.

Whether "More" shows its label. When even the bar without labelled actions or "Select all" doesn't fit, it becomes an icon-only button (still named "More"). The framework measures and passes it (`fitBulkBar`).

Whether "Select all N" fits in the bar. When it doesn't (a narrow container, once every labelled action is already in "More") it moves to the top of "More". The framework measures and passes it (`fitBulkBar`).

Keep the bar visible with nothing selected (its controls disabled).

Where focus goes when the bar closes while it holds focus (the selection emptied under a focused bar button) — typically the row or checkbox the user came from.

A command ran (`optionId` undefined), or a picker's option was picked.

Consumer class, merged onto the bar.

Bindable reference to the bar's root element.
