/**
 * ADR-049: Target platform capability map.
 *
 * Each entry states only what that target actually claims *differently* from
 * `DEFAULT_TARGET`. Spelling every field out per target made adding one
 * capability a nine-place edit (#1307 added two identifier-budget fields and
 * touched all eight entries plus the default), and a target that silently
 * matched the default was indistinguishable from one that had never been
 * reviewed.
 *
 * Lives in `constants/` rather than inside `CodeGenerator` so that whole-program
 * checks can resolve a target too. While this map was module-private to codegen,
 * the only handle `Transpiler` had was the `CodeGenState.targetCapabilities`
 * static — which codegen does not assign until Stage 5, one stage too late
 * (#1307 review).
