Aligns the amber tokens with the family-wide yellow re-tune and refreshes the README brand header.
slatewave.tmux.conf moves the bell indicator and copy-mode mark from #fbbf24 to #fcd34d, and the token names change from amber_400 / amber_700 to amber_300 / amber_500. tmux does not define an ANSI palette of its own, but these two elements visually track ANSI yellow — leaving them on the old pair made the bell read gold against a terminal whose yellow had already shifted.
The README brand header now uses the hexagon icon and a <picture>-based light/dark wordmark swap, sourced from getslatewave.com so future brand updates propagate without touching every repo.
Reinstall or re-source your tmux config to pick up the colors: tmux source-file ~/.tmux.conf.
