<!-- Emoji alphabet (issue Dasher-Android #61, option 2).

Language-neutral: any user can switch here from the toolbar to pick
emoji, then switch back — the engine's alphabet switch API makes this
a pure data asset. Nodes carry multi-codepoint labels (ZWJ sequences,
variation selectors); AlphIO stores the full label string as the
node's Text, so a selection commits the entire sequence atomically
(see ReadCharAttributes: Text = "text" attr, default Display/label).

Groups are kept to 9 topical clusters plus separators: Dasher's
zooming interface needs a shallow tree — two zoom levels to any
emoji. A flat 200-node root would be unusable.

Frequencies: training_emoji.txt provides mild ordering priors
(common juxtapositions); without training the engine falls back to
symbol-order defaults (NodeCreationManager "Dasher will still work").
NOTE: the trainer matches ONE code point per symbol lookup, so only
single-codepoint emoji are learnable from the corpus. The 31
multi-codepoint nodes (ZWJ sequences, VS16 variants like ✈️) always
take default frequencies — a longest-match trainer would be needed
to train those (engine follow-up, not blocking).
