Reserved visibility annotation rejected by semantic analysis.

# =============================================================================
# 保护 — Reserved visibility annotation rejected by semantic analysis.
# =============================================================================
#
# What this teaches:
#   • Reserved keyword — `@ 保护` is syntactically valid but semantically
#     rejected; it has no active visibility meaning
#   • This demonstrates how Faber reserves syntax for future use without
#     committing to semantics
#
# Common mistakes:
#   • Expecting `@ 保护` to provide access control — it is reserved and rejected at compile time (SEM018).

# =============================================================================

# @ 保护 is reserved visibility syntax
#
# This exemplum intentionally fails to compile. `@ 保护` is reserved and
# has no active package, subclass, or sibling-file visibility meaning.
#
# GRAMMAR:
#   annotatedDecl :← '@' '保护' funcDecl
#
# EXPECTED ERROR:
#   `@ 保护` is reserved and has no active visibility meaning
