// Emoji shortcode interpolation: ":tada:" → "🎉". A curated set of the common
// ones (not the full ~1800 — smaller and less obscure for a family/kids' chat).
// Pure + framework-free so it's unit-testable in Node. Replacement happens on
// send, so the encrypted message stores the real emoji and renders natively
// everywhere (bubbles, previews, notifications). Only known names convert, so
// URLs and times like 10:30 are left alone. Easily extended — just add entries.
