# install-fish-to-bash.sh — migrate this NoSignal box from fish to bash, matching
# the Omarchy bash setup. Everything ships in this folder so it survives a wipe.
#
# Applies:
#   1. Vendors Omarchy's default/bash tree -> ~/.local/share/omarchy/default/bash
#   2. Installs ~/.bashrc (Omarchy template + Caelestia colour-scheme line)
#   3. Points kitty + foot at bash
#   4. Replaces the two Hyprland helper scripts with bash ports (kept at their
#      .fish paths so the stock keybinds.conf / hyprland.conf keep working)
#
# Idempotent (safe to re-run). Backs up an existing ~/.bashrc once.
# Does NOT remove the fish package — see README.md.
