/**
 * Chrome labels for DSH's shared `MarkdownText` (DSH
 * 0.1.2-alpha contract): the renderer takes a REQUIRED nested `labels` prop
 * — `labels.code.copyLabel` / `labels.code.copiedLabel` for the fence copy
 * buttons plus a screen-reader-only `labels.footnotes` heading — and the
 * MarkdownText/CodeBlock are cordis-free, falling back to HARDCODED Chinese
 * when the labels are omitted, so every render site threads the plugin
 * dictionary's localized pair through here (re-evaluated per render).
 * `footnotes` is left empty (the heading is sr-only; give it a real string
 * only if a locale key ever earns its place in all 19 dictionaries).
 *
 * DSH 0.1.7-rc.1 added `labels.code.toolbarLabels` (language name + wrap
 * toggle + copy). Supplying it is what swaps the legacy info-string banner for
 * the host's code card, and the three strings are REQUIRED once supplied, so
 * every site that builds the flat pair has to carry them too — the code card
 * must look the same in the transcript, the diff card and the editor preview as
 * it does in DSH's own chat.
