tmux-net: trailing space after the ✕ offline glyph for status-bar padding

- tmux-ip: show the first directly-held public/WAN IP on a non-tunnel interface,
  else the LAN/private IP. No external 'what's my IP' lookup and no DigitalOcean
  special-case (a droplet's eth0 public IP is found by the same interface scan);
  RFC1918/link-local/CGNAT classed as not-WAN, so a NAT'd box shows its LAN IP.
- tmux-net: show ✕ when there's no local IP and no VPN tunnel (offline). VPN ⇡
  overlay unchanged.
- .tmux.conf: window-status icon + path now native tmux formats (no per-redraw
  #() forks); tmux-window-icon kept as fallback.

+## Rainbow output (lolcat)
+
+`zsh/lolcat.zsh` wires [lolcat](https://github.com/busyloop/lolcat) (Debian's
+`/usr/games/lolcat`, busyloop's Ruby build — 24-bit truecolor) into a few shell
+helpers. lolcat auto-detects a tty — it colorizes straight to the terminal but
+passes text through plain when piped onward, so use `-f`/`--force` to colorize
+mid-pipeline.
+
+### Opt-in, per command
+
+Prefix any command to rainbow its output:
+
+```sh
+lol fastfetch
+lol git log --oneline
+lol ls -C                 # -C keeps columns: a piped ls otherwise goes single-column
+lolf git diff | less -R   # force color so it survives down a pipeline
+```
+
+### Shortcuts
+
+```sh
+rcat file.txt             # rainbow cat
+rls -la                   # rainbow ls, columns preserved
+some-cmd | rless          # rainbow + pager (less -R)
+```
+
+### Session toggle
+
+Rainbow *all* shell stdout until you turn it off:
+
+```sh
+rainbow_on                # everything is rainbow now
+...
+rainbow_off               # back to normal
+```
+
+Novelty only: it garbles full-screen/interactive programs (vim, less, htop,
+fzf, ssh) and the prompt, and buffers streaming output. Doesn't touch stderr.
