/**
 * View-config generation for react-native component specs, without babel.
 *
 * `@react-native/codegen` builds a full CodegenSchema with @babel/parser and
 * emits the module with @babel/generator, which is the last thing in the native
 * pipeline that runs babel at all: 11,774 babel calls per bundle of the contrast
 * app, every one of them from codegen. The view config itself is a plain object
 * literal, so it can be read off the spec's own AST and printed as text.
 *
 * Only what a view config needs is modeled here: the prop list in declaration
 * order, the five prop types that get a custom attribute descriptor, the two
 * event handler shapes, and the command list. Everything else about a prop's
 * type is irrelevant to the runtime, which is why the generated `validAttributes`
 * is almost entirely `true`.
 *
 * TypeScript specs are parsed with oxc. React Native's own specs are Flow, which
 * oxc cannot parse, so those go through hermes-parser (which is not babel).
