 * module.ts and generate-css-file.ts, which is exactly the kind of drift resolveDefaultSizeKey
 * was written to prevent for the default key specifically.
 *
 * Also reorders the merge by real (parsed) size, ascending, rather than leaving it in
 * default-keys-then-custom-keys insertion order — a size picker iterating `Object.keys()`
 * (e.g. the playground) would otherwise jump around non-monotonically once custom keys like
 * `xs`/`huge` are appended after the defaults. Unparseable values (CSS vars, `clamp()`, design
 * tokens) keep their relative position instead of being sorted, since their real size isn't
 * knowable at build time.

 * substitute on its own — for `iconSizeDefault` it resolves to `'sm'` (its literal declaration
 * order), not the documented default — so it's only used as a fallback when 'md' isn't a
 * configured key. Shared between build-time codegen (module.ts) and the runtime fallback
