Angle-bracket generic parameters on functions and declarations.

# =============================================================================
# generics — Angle-bracket generic parameters on functions and declarations.
# =============================================================================
#
# What this teaches:
#   • Type parameters — Functions and types can accept angle-bracket generic parameters like `<T>`.
#   • Magnitudo parameters — Compile-time integer parameters use the `आकार` keyword.
#
# Common mistakes:
#   • Forgetting that `आकार` declares a compile-time integer generic parameter — regular types use bare `<T>` syntax.
#
# See also: प्रकार, फलन
# =============================================================================

# generics — angle-bracket parameters (replaces removed prae प्रकार)
#
# GRAMMAR:
#   genericParams :← '<' (ident | 'आकार' ident) (',' (ident | 'आकार' ident))* '>'
#
# EXPECTED OUTPUT:
#   No आरंभ — declaration or test-runner surface only.
#
# BACKEND:
#   declaration-only generic surface (whitelist: prae/prae.fab). Cross-ref: generic/generic.fab.
