5-post design walkthrough of a branch-free 8-bit/word color-forth variant for code generation: ~62 dict entries/page with paging, call/return inlined by the compiler, branch-free compile + branch-free execution, lookup-table pre-compile writes unaligned 8-bytes. Intended for tiny self-contained chunks that include their own codegen. Whitney-esk in single-char vars, non-Whitney in no higher-order arrays.
