/**
 * Share / Export / Present format-picker (share/show) — transcribed from
 * docs/design-reference/extracted/modal-share.html.
 *
 * A 640px card (README.md §1, binding) inside the app's shared modal
 * <dialog> (see application.html.erb's `<dialog data-controller="dialog">`).
 * The formats are full-width cards stacked with a 0.45rem rhythm; the chosen
 * one fills teal with a 2px rule. Scope is a row of chips under a hairline.
 * The footer is the tray footer: actions left, the workbook download pushed
 * to the far end.
 *
 * Literal pixel type from the capture is written calc(Npx * var(--text-scale)),
 * the convention modules/hub.css established.
