// `**` array repetition: `[_]u8{0} ** SIZE` builds an array by repeating a
// comptime-known operand — the canonical zero-init for fixed buffers, lookup
// tables, and pointer slots. The shapes here are the load-bearing ones:
// a struct-field default sized by a named constant, the anonymous-tuple
// form `.{0} ** N`, a typed non-u8 element (`[_]?*T{null} ** 64`), and a
// parenthesized count expression.
//
// Lives in examples/register/ (post-v0.5 grammar — the frozen stage0
// bootstrap compiler cannot parse it; gated by `zig build fixpoint`).
