# =============================================================================
# สคีมา — Declares an application-owned relational heading (experimental)
# =============================================================================
#
# What this teaches:
#   • Relational headings — `สคีมา Name { ... }` names the columns an application reads from a database result.
#   • Declaration only — a สคีมา carries column metadata, not a runtime value, so a program that declares one still runs unchanged.
#
# Common mistakes:
#   • Giving a สคีมา methods or `เติมเต็ม` — a สคีมา is a heading, not a ชนิด; both are rejected at parse time.
