/**
 * User-facing text for the reader UI (control labels, screen-reader announcements, panel and
 * loading text). English by default; a consumer overrides any subset via the `strings` option.
 *
 * Static entries are plain strings. Entries that mix in a number or piece of text are functions,
 * so a translation can handle pluralization and word order that a `{placeholder}` string cannot.
 * Page numbers passed to these functions are already 1-based (display) values.
