A file that fails to attach now says why

If a file you attached to the AI chat could not be uploaded, pressing Send used to do nothing - no message, no explanation. That is fixed:

• Attach a file before you sign up. A file added to your first prompt now travels with it. Before, the message could fail to send right after you created your account.
• You are told at once, by name. When a file cannot be uploaded, Playcode says which file and why - it could not be read from your device (common with files still syncing in OneDrive, iCloud, or Dropbox), your storage is full, the connection dropped, or it is not an image your browser can open - and what to do next.
• Send never goes quiet. If a message cannot go because of a failed file, Playcode tells you so. Your text and your other files stay exactly where they were.
• Nothing gets dropped. When one file in a batch failed, the files that did upload used to disappear from your draft. They stay now.
