const app = mvfm(prelude, zod);
const prog = app({ value: "string" }, ($) => {
  return $.zod.string().optional().parse($.input.value);
});
await fold(
  defaults(app),
  injectInput(prog, { value: "hello" })
);

const app = mvfm(prelude, zod);
const prog = app({ value: "string" }, ($) => {
  return $.zod.string().optional().parse($.input.value);
});
await fold(
  defaults(app),
  injectInput(prog, { value: "hello" })
);

const app = mvfm(prelude, zod);
const prog = app({ value: "string" }, ($) => {
  return $.zod.string().optional().parse($.input.value);
