Platform Formatting How-Tos
Every platform has its own formatting dialect: LinkedIn renders Unicode, WhatsApp parses markdown-ish syntax, Slack ships its own toolbar, Discord supports a tiny subset of markdown. The "how do I bold this?" answer changes per app, per surface, sometimes per OS.
This hub is the working reference. Each guide shows the exact steps, the gotchas (line breaks on Instagram, mobile vs desktop rendering), and the fastest tool to do it from a phone.
