#   source ./bashmoji.sh            # in a script: defines BM_* glyphs/colours + bm_* helpers
#   ./bashmoji.sh                   # run it: shows every glyph, colour and helper

#
# Rules this file keeps, so sourcing it can never break the script that sources it:
#   · every name is prefixed BM_ (variables) or bm_ (functions) — it never assigns
#     PATH, PORT, HOME, NODE or any other name a script or the shell already uses;
#   · it runs nothing and prints nothing when sourced;
#   · it works in bash 3.2 (macOS) and later: no associative arrays, no ${x,,};
#   · it degrades by itself: no colour when stdout is not a terminal, when
#     NO_COLOR is set (https://no-color.org) or TERM=dumb; ASCII instead of emoji
#     when the locale is not UTF-8 or BASHMOJI=plain.
#
# Overrides:  BASHMOJI=plain|emoji   BASHMOJI_COLOR=never|always   NO_COLOR=1
