One openemoji.json that states coverage against a Unicode version, the
licence, and who or what drew the set (made_by plus the W3C AI disclosure
vocabulary), and glyphs named by fully-qualified codepoint sequence.
Custom emoji get x- keys with shortcodes; skin tones name their base;
rendered emoji keep the character as alt. Mapping from Mastodon, Slack,
Discord and CLDR.
Landing page shows 19 glyphs drawn by the reference implementation,
`emoji` in profullstack/cli-tools.
