#
# What this teaches:
#   • Relational headings — `lược_đồ Name { ... }` names the columns an application reads from a database result.
#   • Declaration only — a lược_đồ carries column metadata, not a runtime value, so a program that declares one still runs unchanged.
#
# Common mistakes:
#   • Giving a lược_đồ methods or `thực_thi` — a lược_đồ is a heading, not a kiểu; both are rejected at parse time.
