/**
 * Amount formatting for everything a campaign puts on screen.
 *
 * One rule, applied everywhere: **decimals appear only when there is a fraction
 * to show.** A goal of 10000 reads "10,000", a raised total of 3750 reads
 * "3,750", and 3750.50 still reads "3,750.50". A column of ".00" says nothing
 * except that the site is running software that cannot tell the difference.
 *
 * It lives here rather than at each call site because there were six of them
 * across two plugins — the progress goal, the summary total, the minimum-donation
 * notice, the amount chips, the campaign-list column and Pro's donors wall — and
 * they already disagreed: some used `number_format`, Pro used `number_format_i18n`,
 * and the amount chips used bare float interpolation, which printed "€10.5" for
 * ten pounds fifty and "€1000" with no separator at all.
