# shellcheck shell=bash
# ~/.bashrc — bash's interactive entry point, the counterpart of config/zshrc.
#
# Layering (see config/env's header for the full picture):
# config/env environment, every shell, every mode
# config/profile shared interactive layer (aliases, history, theme, profile.d)
# config/bashrc bash-specific interactive bits <- this file
# config/zshrc zsh-specific interactive bits
#
# bash and zsh disagree about which file a *login interactive* shell reads:
# zsh reads ~/.zprofile AND ~/.zshrc, but bash reads only ~/.profile and never
# ~/.bashrc. So the two entry points source each other, guarded both ways:
# - entered here (interactive non-login) -> we source ~/.profile below
# - entered via ~/.profile (login) -> it sources ~/.bashrc at its end
# The __dotfiles_* flags below make sure exactly one direction fires.
# Non-interactive bash never needs any of this, and a login *non*-interactive
# shell can reach here via ~/.profile. Bail out before doing any work.
