> *Stacks on:* OPENNLP-1868.
> *Summary.* Add an opt-in, offset-aware rung that folds emoji to emoticon
> (expansion) and emoticon to emoji (contraction), backed by a
> provenance-tagged lookup of the same shape as OPENNLP-1868. A
> supplementary-plane emoji is also the two-UTF-16-units-to-one case, so it
> exercises the contraction path. Most rows are \{{UNSPECIFIED}} (no governing
> standard for the mapping); anchor on CLDR where a direction can be (emoji
> short-name).
> *Acceptance criteria.*
> * A bidirectional, opt-in, offset-aware emoji/emoticon rung with round-trip
> tests in both directions, including a supplementary-plane emoji.
> * Lookup carries provenance (\{{EMOJI}}/\{{EMOTICON}} fold types,
> \{{CLDR:annotation}} or \{{UNSPECIFIED}}).
> * Consistent \{{WordType}}-level classification so emoji and emoticons are
> treated as one class for token counts and ML feature generation (settle:
> punctuation-like bucket vs a dedicated emoji \{{WordType}}).
