# Fails if hardcoded theme hex values appear anywhere in the repo outside:
# - basic/.config/themes (the single source of truth)
# - term/.config/tmux/plugins/ (vendored upstream, stow-ignored)
# - term/.config/yazi/theme.toml (declared mirror: yazi has no include)
# - term/.config/starship.toml (declared mirror: starship has no include)
# - hypr/.config/hypr/noctalia.lua + hypr/.config/kitty/themes/noctalia.conf
# (Noctalia template output: shell-owned, gitignored, regenerated from
# the active palette on every theme change)
# - test/ + docs (may quote values in prose)
#
# Run with: bash basic/.config/themes/scripts/sync-theme.sh
# test/lint.sh invokes it as part of `make test-lint`.
