# `src/core/transforms.py`

Tag-schema value transforms for miniDLNA folder names.

Applied when building a folder name from a tag value — the tag keeps its exact
value (e.g. rating 87 → tag "Hodnocení/87"), while the folder groups it
(→ "…/80–89 %"). Config-driven and extensible via `TAG_TRANSFORMS`.

## Functions

### `rating_band`

*function · line 11*

```python
rating_band(rating: int) -> str
```

Bucket a 0–100 rating into a ten-point band label (e.g. "80–89 %").

The top bucket spans 90–100 % so a perfect 100 still lands in a band.

### `_decade_band`

*function · line 21*

```python
_decade_band(value) -> str
```

`decade_band` transform: pull the leading integer and bucket it.

### `apply_transform`

*function · line 35*

```python
apply_transform(value: str, transform: Optional[str]) -> str
```

Apply a named tag-schema transform to a value, returning a string.
