Plan was originally written assuming `transform: rotate` would work
in GTK 3 CSS; it doesn't. Spec was already updated in 1646dfc; this
brings the plan in line so historical readers see the same approach
across spec, plan, and code.

No CSS rule targets .tray-drawer-child — speculative key with no
consumer. YAGNI cleanup.

GTK 3 CSS (used by waybar) treats `transform` as a fatal parse error,
so the rotation approach killed waybar entirely. Use a color shift
from @tn-fg-muted to @tn-fg as the expanded-state feedback instead.
Matches the existing style.css convention (battery/cpu/temperature
states all use color shifts, not transforms).
