🛣 (U+1F6E3) heads the Trophy case's Longest distance board, and it pushed that
heading's row a column past the border. Both width authorities call it one cell —
it sits outside Emoji_Presentation and its East-Asian width is Neutral — while the
font draws it as a two-cell colour glyph.
That is a new shape for the wide set, which until now held VS16 bases the narrow
verdict got wrong (🛩, whose selector-stripped base would otherwise collapse to
one). Nothing narrowed the motorway; it was never measured right in the first
place, so it overran its row on any screen that pads to a width. The fix is the
same either way — force the base to two in Rich and in prompt_toolkit — so the set
is now `_DEFAULT_WIDE_BASE`, seeded with both confirmed glyphs and still overridden
outright by MESHTERM_WIDE_EMOJI.
Curated, as always, because which glyph a terminal draws wide is the font's
business and a cursor probe reads the PTY, not the renderer.
