Braced canonical @ tùy_chọn CLI option record.

# =============================================================================
# tùy_chọn — Braced canonical @ tùy_chọn CLI option record.
# =============================================================================
#
# What this teaches:
#   • Braced option annotation — `@ tùy_chọn { binding = NAME, … }` configures a
#     CLI option with named fields
#   • Option fields — binding, ngắn, dài, kiểu_tên, mô_tả, and toàn_cục
#     control how the option is parsed and documented
#
# Common mistakes:
#   • omitting required fields like `binding` or `dài` in `@ tùy_chọn` braced records; boolean flags need `kiểu_tên logic`
#
# See also: tùy_chọn, cli, annotation-sugar
# =============================================================================

# Braced @ tùy_chọn — canonical option record
#
# TARGET: annotation-sugar stage 2
# PAIR: sugar `@ tùy_chọn NAME ngắn \"x\" ...` (see tùy_chọn/optio.fab)

# tùy_chọn — Declares a CLI option annotation.
# =============================================================================
#
# What this teaches:
#   • CLI options — `@tùy_chọn` declares named flags (short and long forms) for CLI subcommands.
#   • Option metadata — Each option specifies binding, type, description, and optional default values.
#
# Common mistakes:
#   • Declaring a boolean tùy_chọn without at least one of ngắn or dài — boolean flags need a flag form to be usable.

# GRAMMAR:
