# ken-trade-flash.sh — flash "NEW TRADE BY KEN" in blinking red on the CURRENT iTerm2 pane.
# Resolves this session's pane tty from the ITERM_SESSION_ID guid via iTerm2 AppleScript,
# then writes a bold blinking bright-red banner + terminal bells straight to that tty device
# (not via 'write text', so it paints on screen without injecting into the Claude prompt).
# Usage: ken-trade-flash.sh "TICKER side count @ price"   [detail line optional]
