+### Nested tmux (C-g on rocky)
+
+Earth (outer tmux) uses the default **C-b** prefix. Rocky (inner tmux) uses **C-g** so you can control both layers.
+
+**Visual distinction — you'll never confuse the two:**
+
+| Layer | Prefix | Active Border | Status Bar | Pane Indicators |
+|-------|--------|---------------|------------|-----------------|
+| **Earth (outer)** | `C-b` | **Magenta** | White-on-purple | Default blue |
+| **Rocky (inner)** | `C-g` | **Bright Red** | **Black-on-orange** with `[ROCKY]` label | **Red/orange** pane numbers, border labels |
+
+**Workflow:**
+| Key | Action |
+|-----|--------|
+| `C-b c` | Create window in outer tmux (earth) |
+| `C-g c` | Create window in inner tmux (rocky) |
+| `C-b b` | Send `C-b` through to inner tmux |
+| `C-g g` | Send `C-g` through to inner-inner tmux |
+
+Rocky config is in `~/.config/tmux/tmux.rocky.conf` and sourced from `tmux.local.conf`:
+
+```sh
+# ~/.config/tmux/tmux.rocky.conf
+unbind C-b
+set -g prefix C-g
+bind C-g send-prefix
+
+# Drastic RED/ORANGE color scheme
+set -g pane-active-border-style 'fg=brightred,bold'
+set -g status-style 'bg=colour208,fg=black,bold'
+set -g status-left ' [ROCKY] #[bg=brightred,fg=white] #S '
+set -g window-status-current-style 'bg=brightred,fg=white,bold'
+set -g window-status-style 'bg=colour208,fg=black'
+
+# Active pane indicators
+set -g display-panes-colour colour208 # prefix+q pane numbers
+set -g display-panes-active-colour brightred # active pane number
+set -g pane-border-status top # show pane info on borders
+set -g pane-border-format '#[fg=colour208] #{pane_index} #[fg=brightred]#{pane_title} '
+set -g window-status-current-format ' #I*#[bg=brightred,fg=white] #W '
+```
+
+This is deployed by the `home_tmux_rocky` Rex task (runs only when `hostname =~ /rocky/`).

### Building taskwarrior from source
Rocky 9 does not ship `task`/`taskwarrior`. v3.x requires Rust; v2.6.2 compiles cleanly.

+**tmux 3.2a compatibility note:** The dotfiles `tmux.conf` includes `set -g extended-keys-format csi-u` (tmux 3.3+). On rocky this line is automatically stripped by the `home_tmux_rocky` Rex task. If you deploy manually, remove or comment out that line.
