+# Fix Web Terminal Clipboard
+
+## Problem
+
+Users cannot reliably copy terminal output from the browser terminal. Browser copy shortcuts may be forwarded to the terminal as input instead of copying the xterm selection, and paste behavior differs by bracketed-paste mode.
+
+## Required behavior
+
+- Copying a selected terminal region with standard browser shortcuts (`Ctrl/Cmd+C`) copies text to the system clipboard without sending an interrupt to the terminal.
+- Copy requests expose the xterm selection as plain text.
+- Pasting plain text is handled once and follows bracketed-paste mode when enabled.
+- Normal terminal interrupts still work when there is no active selection.
