## Coding Conventions

Apply the convention section in the guide you open. Odoo 19 runtime behavior,
then existing stable-addon style, takes precedence; keep diffs focused.

- Module naming, assets, JavaScript, CSS, and SCSS: development guide.
- XML formatting and IDs: data, actions, reports, security, and views guides.
- Python, recordsets, transactions, and translations: model, field, decorator,
  performance, transaction, and translation guides.
