The ten ring names settled between gospel and exp, derived from exp's ringFor()
rather than hand-numbered so the numbering cannot drift from the code that
produces it. The screen legend already renders these words, so a printed sheet
using them cannot disagree with the screen.
Written as vocabulary in the header a caller reads, and deliberately NOT as a
prop default. One cell is still open on the Driver's row 89 — "people" versus
the brief's "culture" in column 1 — and if he keeps his, exactly three cells
change, 1, 4 and 7, and nothing else: not the numbering, not the columns, not
the colours.
A default would bake a provisional word into every consumer that forgot to pass
one, and would make this component the thing that decided a Driver question.
Same reason ShareCalendar refuses to name its own metric.
