3.1.0

• Pairing again — after reinstalling, or on a fresh copy of the vault — takes the earlier pairing's place instead of using another device slot.
• Unpair removes this vault from your account, freeing its slot, and forgets its sign-in.
• The README now says what the plugin needs: a dropit account (free), which limits depend on your plan, and the one service it talks to.

Install: Settings → Community plugins → Browse → dropit (once listed), or put main.js, manifest.json and styles.css into .obsidian/plugins/dropit/.
