 How to reference them:

 Rule of thumb:
 - If the logic is only used by one module, prefer that module's `hook.php`
 - If the logic will be reused by several modules/pages, create a global hook in `hooks/`
+- Return arrays from hooks; do not use `echo json_encode(...)` or `exit`

 ## Creating a Module — Full Workflow
 
-If the module needs server-side logic, dynamic data processing, form handling, or reusable backend behavior, read `docs/hooks-and-api.md` before creating `hook.php` or any global hook.
+If the module needs JavaScript, you MUST read `docs/css-js-conventions.md` before writing `index-base.tpl` or `script.js`.
+If the module needs server-side logic, dynamic data processing, form handling, or reusable backend behavior, you MUST read `docs/hooks-and-api.md` before creating `hook.php` or any global hook.
 If the module will call hooks from Twig, also review `docs/twig-filters.md` for the `hook` filter syntax.
 
+Hard rules for module files:
+- `index-base.tpl` is for HTML/Twig only
+- `script.js` is for module JavaScript
+- `style.css` is for module CSS
+- `hook.php` is for server-side logic
+- Do NOT embed `<script>` tags in `index-base.tpl`
+- Do NOT put PHP logic in `index-base.tpl`
+
 1. **Read style reference** (steps above)
 2. **`acai-write`** — Create the module files directly (`index-base.tpl`, `style.css`, `script.js`, optional `hook.php`) using project-relative paths and complete file contents.
    - If the server-side logic belongs only to that module, create `template/estandar/modulos/<module-id>/hook.php`
    - If the logic should be reused across modules/pages, create a global hook in `hooks/hooks.<hook-id>.php`
    - Inside the module, reference its own hook with `/hooks/<module-id>/`
+   - Example: module folder `template/estandar/modulos/buscadorapartados_hjd8s/` -> hook endpoint `/hooks/buscadorapartados_hjd8s/`
 3. **Automatic compile** — Writing `index-base.tpl` automatically creates the generated template placeholders and triggers compilation. `compile_module` is only a manual recovery tool if you need to force a recompile without changing the file.
 4. **`add_module_to_record`** — Adds the module to a page. Response includes `sectionId` — use it directly in the next step.
 5. **`set_module_config_vars`** — Fill variables with content. Response includes `uploadFields` with `{ fieldName, recordNum }` for each upload variable.
