 ## Conventions for AI assistants
 
 - **Never write to `GeneratedField`s** (`duration_calculated`, `duration_total`, `price_per_game`, `days_to_finish`). They are computed by the database.
+- **Name variables with complete words** — readable, unabbreviated identifiers in both Python and JavaScript (e.g. `template` not `tpl`, `event` not `e`, `element` not `el`, `removeButton` not `removeBtn`, `option`/`value` not single letters in loops). This applies to new code and to code you touch.
 - **Use `render_page()` not `render()`** for all full-page HTTP responses. Import from `common.layout`.
 - **Build UI with Python components** from `common.components`, not raw HTML strings or Django templates. `SafeText` children pass through unescaped; plain strings are auto-escaped.
 - **Filter views** accept `?filter=<JSON>` (structured) and fall back to `?search_string=` (free-text). New filter criteria go in `games/filters.py`; new criterion types go in `common/criteria.py`.
