/**
 * OSS attribution: the row of pills under a product's name in ProductFooter.
 *
 * One source of strings: lib/constants/products-metadata.ts. A small pill row
 * (License, GitHub, Stars); the heading and the frame are ProductFooter's.
 *
 * Stars come from lib/data/oss-stars.json, which scripts/sync-oss.ts writes once
 * per build, the starred repositories alone. Asked from the browser they cost every reader one of GitHub's sixty
 * unauthenticated requests an hour and answered 403 once those ran out. A
 * repository the snapshot does not hold draws no Stars pill; the block does not
 * depend on a count.
 *
 * The three pills are `Chip`, this site's hairline outline. What the rule
 * leaves to a caller is the SIZE — a chip and a badge are the same outline at
 * two of them — so the padding and the rung are stated here and nothing else
 * is. The GitHub pill is the one that is a link, and `Chip` is
 * already the rule for that.
 *
 * The name lost its `hz-` prefix when this document's rules did, and this call
 * site did not follow: with no rule behind it each pill was a full-width block
 * with no outline, rather than a chip. `Start.tsx` carries the measurement.
