## Do not use Ellipsis for *path operations* or Pydantic models

Do not use `...` as a default value for required parameters, it's not needed and not recommended.

Do this, without Ellipsis (`...`):

```python
from typing import Annotated

from fastapi import FastAPI, Query

.filter-check-item:hover {
    background-color: #f4f5f7;
}

.filter-check-item .filter-check {
    margin: 0;
    flex-shrink: 0;
}

.filter-check-label {
    overflow: hidden;
    text-overflow: ellipsis;
    white-space: nowrap;
}

.filter-dropdown-footer {
    padding: 0.25rem 0.5rem;
    border-top: 1px solid #ebecf0;
    text-align: right;
}

.filter-clear-group {
