// Bilingual content schema for the Astro migration.
//
// Both `en` and `pt` are required on every localized field. A missing `pt`
// must fail the build — silent English fallback is how a bilingual site
// quietly becomes monolingual. Do not change `localized` to make a field
// optional without an explicit reason in a code review.
//
// Layout follows the brief in plans/astro-refactor/task-04-content-schema.md:
//   - phases / providers / efforts / skillSources / handsOnPrompts /
//     skillInstallPrompts — guide content carried over from app.js
//   - chapters              — copy for /models/, /agents/, /skills/, /summary/
//   - reviews               — the 24 entries from skills-review/catalog.js
//
// This file is schema only. Tasks 05 and 06 fill the entries; the content
// migrator agent owns this file end-to-end.
