# Companion for fzf — resolve and apply the configured color theme.
# fzf's own --color flag natively takes key:hex pairs, so no format conversion
# is needed here (unlike psreadline, which converts hex to ANSI escapes).
# Register-DFTool's env-block step already (re)sets $Env:FZF_DEFAULT_OPTS from
# fzf.json's non-color flags on every call, before this companion runs, so
# appending the resolved --color=... string here is always idempotent.
