Paste Fold

A prompt composer that recognises a large paste — a log, a table, a long email, code — and instead of flooding the field spills it in as a sheet of its first lines, then folds it on springs.glide into a labelled block showing its kind, line count and first line, with the caret already after it so you keep typing. Peeking flips the composer to the block's numbered lines with the height gliding, and Trim keeps only the lines you mark (Errors only marks a log's errors in one press); over the character limit the meter turns danger and Send holds. The message is a flow of real textareas and block chips: Left at the start of a run or Backspace there selects the block before it, Space peeks inside, Backspace removes it, and on a phone blocks wrap as full-width chips.
