Key gotchas

• Param is `text` not `emoji`/`shortcode` — both fromshortcode and toshortcode use text. info uses input.
• GitHub-style shortcodes — :+1: not :thumbsup:, :tr: not :flag_turkey:. :thumbsup: passes through unrecognized.
• Skin tone modifiers DROPPED in shortcode — 👍🏽 → :+1: (not :+1::skin-tone-4:). Info still shows the modifier codepoint.
• from_shortcode/to_shortcode return PLAIN TEXT, not JSON. Only info returns JSON.
• Unknown shortcodes preserved silently — no error, just passed through unchanged.
• ZWJ sequences work — 👨‍💻 → :man_technologist: with all constituent codepoints.
• Flag sequences work — 🇹🇷 → :tr: (regional indicator pairs).
• Variation selectors handled — ❤️ shows U+FE0F in codepoints.
