+# PATH — fish is the first-class shell, so it owns its own PATH setup
+# rather than relying on rc.common (which serves bash/zsh). Mirrors:
+#   rc.common: export PATH="$HOME/bin:$HOME/.local/bin:$PATH"
+#
+# Without this, a fish login shell (e.g. SSH'd into Linux where fish is the
+# login shell) never sees ~/bin, so tools installed there — notably starship
+# (setup/tools.sh installs it to ~/bin) — are invisible and the starship
+# prompt block in config.fish is silently skipped.
+#
+# fish_add_path is idempotent. -g keeps it session-global (driven entirely by
+# this committed config, reproducible across machines, no per-host universal
+# vars) and -p prepends in the given order.
