Declares an application-owned relational heading (experimental).

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

# 架构 — relational heading declaration
#
# GRAMMAR:
#   schemaDecl :← '架构' IDENTIFIER '{' (schemaColumn (NEWLINE schemaColumn)*)? '}'
#
# EXPECTED OUTPUT:
#   架构 declared

架构 Persona {
    column string 名称
    column int aetas
}

main {
    print "schema declared"
}

Expected output:

schema declared
