+Opens the offline fish shell configuration manual. Without flags, opens
+the Markdown source in the best available pager (ov > bat > man > less >
+cat). If SECTION is given, jumps to the first heading matching that
+keyword (case-insensitive; checks fish-config.index aliases first).

+Flags:
+  --html / -w   Open docs/html/index.html in the default browser.
+                Detects the browser via xdg-mime x-scheme-handler/https,
+                then known binaries, then xdg-open as last resort.
+                Respects $fish_help_browser and $BROWSER.
+  --man  / -m   Open docs/fish-config.1 via man -l directly.
+  --help / -h   Print usage and navigation key reference.

+Synopsis:  config-update [-h] [-n] [-f]
+
+Pulls the latest fish configuration from the upstream repository
+(https://git.rootiest.dev/rootiest/fish-config.git) into \[ti]/.config/fish.
+The remote URL is hard-coded, so this works on fresh clones with no git
+remote configured. All git output is suppressed; colored messages report
+fetch and merge status. After a successful pull, run \[ga]exec fish\[ga] to
+reload.
+
+Flags:
+  --dry-run / -n   Fetch and show available commits without applying them.
+  --force  / -f    Stash local changes, pull, then restore the stash.
+  --help   / -h    Show usage.
