_mixrc

-- ~/.rc/_mixrc — public Mix shell toolkit (wrapper)
--
-- Sourced from ~/.mixrc (the user's personal trampoline; bash-parallel
-- to ~/.bashrc → ~/.sh/_shrc). Provides shell-foundational env that the
-- _lib/ topic modules can rely on ($ostyp, $SUDO, $HOME), then
-- glob-loads ~/.rc/_lib/*.mix in lexical order.
--
-- This file is the public, shareable wrapper. No machine-local content,
-- no secrets. User additions go in ~/.mixrc (machine-local, not in git)
-- or in topic modules dropped into ~/.rc/_lib/ that the user owns.
--
-- The mix binary itself lives in the sibling repo github.com/markc/mix;
-- see README.md for the full manual and install steps.
